GE Opal Rebuild Saga - Fix Leaking, Screeching, Scaling, and More!

I obtained a GE Opal Profile 1.0 Nugget Ice Machine on OfferUp. It was a package deal that included an all-in-one coffee machine. Two $400 machines for $50 was too good to pass up. After filling and rinsing, I found out why they wanted to be rid of it: it sounded like a wailing banshee! There was also a grinding noise. And it leaked. What had I gotten myself into?

I’m hoping what I learned will help you keep yours running too. Be sure to reach out if you have any questions or comments: dan@danlearnsstuff.com

Models

The pictures in this thread refer to what is colloquially known as Opal 1.0. It is listed on the back as OPAL01GEPSS. It has a 9-hole Cap where the ice exits the auger channel.

 

A 2.0 model has a broadly similar construction and disassembly procedure, but it may require different tools and parts than what is listed here.

Problems

Below are the types of issues that I have personally fixed on my machine:

• Have a fast leak? If it can’t hold water at all, replacing the auger seal will stop the worst leaks.
• Does it screech or whine after water has begun to freeze? Replacing the bottom seal will help this.
  
• Does it screech or whine immediately after starting, but it goes away once it gets cold? Replacing the upper auger bushing will help.
• Have white particles in your ice? Do you use tap or filtered water? Descaling will help. Switching to distilled or Reverse Osmosis water will extend the life of your machine greatly.
• Have black particles or sludge that are not mold? Replacing the upper auger bushing will help too.
• Have black particles that may be mold? A chlorine wash will help.
  

This page captures images and step by step directions for fixing the above auger-related issues. They are mostly centered within the auger chamber itself, but disassembly instructions can help you diagnose and treat a variety of problems. There are other tutorials online that can help you swap the drain lines and diagnose fan and pump problems that are separate from auger wear and tear.

Parts

Throughout this guide, I refer to replaceable parts that can wear down over time and can be replaced using various sources online. Most commodity parts and supplies can be found on Amazon. Some were specially engineered for this machine, and the community has people that are machining replacements you can purchase to keep our babies running well past their original lifetimes.

• 3/4” Auger Seal
• Auger Bushing
• H1 Food-safe Grease
• Distilled White Vinegar
• Ice Machine Cleaner

Disassembly for Auger Maintenance

 Getting into the auger is a bit more difficult than the water pump and other areas. You'll need the following tools:

• Phillips head screwdriver (with long shaft for deeply inset screws)
• Electric screwdriver with phillips head bit for lots of tiny screws
• Spudger or pry-tool
• 10mm deep socket with extension

To help clean out the auger shaft and reseat auger seals, you may also need:

• Long flat-head screwdriver
  
• Large and long socket extension tool
• Long hooked pick or long and narrow needle-nose pliers

Start by UNPLUGGING THE UNIT. I cannot stress this enough. Make sure it is not plugged in before starting!

Then, drain the unit completely. No water should remain.

You can now begin to tear into the unit by removing the top lid.  4 screws hide under rubber caps. A spudger or sharp steak knife can help remove them. Beware: If they hit the counter, they will bounce everywhere.

Disconnect the wi-fi card cable that hides right under the lid.

Remove all screws from the back panel. Move the drain hoses off the panel, and set the entire panel aside.

Remove the screws from the side panels. This is to expose the screws holding the upper tank to the chassis, and to give you more room to maneuver things. You don’t need to completely remove the surround from the chassis! Just shift it up and out of the groove in the base. Careful! It’s got sharp edges!

Unscrew the upper tank from the chassis.

Unscrew the other two interior screws for the upper tank, pictured here.

This transparent cap is held on by 3 screws and weather-stripping-like insulated moulding. Carefully remove the moulding and unscrew the cap.

Having unscrewed the upper water tank in a previous step, shift it off the black chute. It doesn’t have to move very far.

Unscrew the black chute. You will need a skinny long handled Phillips. The screws may be rusty, so be careful they don’t get stripped. There are two inside screws at the tail of the chute as well.

After the black chute is removed, this styrofoam cap can be removed as well. Carefully wiggle it free. To free up space, you can move the water tank farther away. It might also help to unplug the connectors for the front panel and fullness sensor (black and white, squeeze to separate). Remember to reconnect them!

You have successfully revealed the auger body! A 10mm socket will remove the 4 cap screws. As you loosen them, the cap may spring up. They keep tension on the seal spring.

The auger cap will pull straight up revealing the auger chamber. You can see the white bushing nestled inside the cap.

Using a cloth to help get purchase on the auger shaft, lift the auger straight up and out. It should come up with the spring part of the seal.

And now you can see directly to the bottom of the auger chamber. The seal rests on the bottom between the metal body and the ceramic ring/bushing. NOTE: This picture shows the auger seal seated incorrectly!

Congratulations! You have disassembled your ice maker.

General Maintenance: Descale and Sanitize

If you don't use distilled water or that from a reverse osmosis unit, descaling monthly will keep your unit in tip-top shape.

Clean-out and Regrease

While you have it open, take a moment to check other parts that can get gunked up.

• If your machine is whining, the auger is being eroded and scraped off in the chamber. This can lead the upper and lower tanks getting a dark sediment. Wipe  it out and rinse.
• Check the lines for white sediment. The descaling process can knock these loose, but the pump won’t be able to move it into the tank. You can detach and rinse these pipes as well.
• If you have lots of scale, it may be faster to chip it off with a brass tool. Just don’t scratch the surface of your parts by using anything harder than that.
• Vacuum off fans and grilles to keep your cooling system in top shape.
• Look for leaks and calcium deposits. These are harbingers of bigger problems.

Replace the Auger Seal

A grinding that goes away until the machine cools down or fast leaks from below the chamber through the gear case are most likely due to a bad seal at the bottom of the auger. This multi-part pump seal keeps water in the chamber, and it has rubber, ceramic, and metal parts. It is way over-built for this application, but you need to handle the parts carefully. Order matters, and cleanliness matters.

The ceramic ring sits within the round rubber seal. The other half is a metal seat, spring, and rubber seal. The seat fits on the auger shaft against the helix. The rubber seal on the spring fits against the ceramic ring when properly fit into the chamber. The ceramic is sensitive to oils on your skin. It can degrade faster and affect the seals. Clean it with isopropyl alcohol if you touch it. The rubber seals can use a tiny bit of H1 food-safe grease to help seat them properly.

To replace the pump seal, pull the auger and then use a dental scraper or hooked tool to remove the bottom seal and ceramic ring. Seat the new sitting seal on the auger with the rubber towards the socket.

It can be difficult to seat the new bottom seal in the bottom of the chamber without touching the ceramic. Slip it around a long screwdriver or socket extension, sit the tip of the tool onto the crank, and drop the seal into place. Clean off the tool and press the ceramic down into the crank cavity. If this doesn’t seat well, it will leak immediately and vigorously once you seal it back up. Note: The picture below is wrong! The seal is on the wrong side from the ring! If you have better pictures, please send them my way.

When you reset the auger, ensure the spring is not stuck in its compressed state. It will have some bounce when you put the cap back on.

Replace the Bushing

Is there an unholy banshee haunting your machine? The tell-tale wail is probably the bushing at the top of the auger. It keeps the auger centered in the chamber, but it wears down over time. This leaves the auger to scrape against the sides of the chamber. This causes black sludge and a gradually eroded auger.

eBay seller gweedoh machines his own new bushings from material that it’s much stronger than the stock ones. But from him and buy for life. You can see the size of the worn out bushings versus a new one below.

Each one comes pre-coated with food safe H1 grease as well.

Just pop the old one out and the new one in. The wailing is gone!

Knights of House Caro Mea - The Dark Hand

The Dark Hand, or Manus Tenebrae in High Gothic, is an ancient war machine that traveled the galaxy after The Overgrowth. Eager to reclaim their home world and the forges that wrought these old machines, the knightly house of Caro Mea has joined the Mechanicus expeditionary force. Its pilot keeps the restless machine spirit at the heart of the Dark Hand busy with forest-taming operations. And while the trees of Pholos IV are more hostile than most, recent skirmishes suggest it will be called upon to enter the fray against more heady foes.

After being assembled for 5 years, I finally got the courage to paint this lumbering mech of a Father's Day gift. The under-carriage was a straightforward Leadbelcher with Nuln Oil drybrushed to highlight, and the panels are where I spent most of my time. I'm particularly proud of the blue stripes that give the flat blocks of color subtle depth. In addition, this is my first attempt at decals in some time, and Micro-sol was a miracle-worker at keeping them from being shiny. I used a black Sakura Pigma 005 for writing the name on the chest scroll. The base was mostly an afterthought, and I hope the Necron that was tread underfoot makes a speedy recovery.

Skitarii, Mashal, and Tech Priest Dominus

Just finished these 12 minis, all with a similar palette. I only paint right now, so they are probably not playable on the tabletop, lol.

A different Dominus is the mini that got me back into painting 5 years ago, so it was refreshing to take another crack at this mini after having learned so much! I have learned a ton about blending and layering since then. The robes are richer, the metals poppier, and I am much more precise.

The marshal was a little disappointing, honestly. I wanted so much more from this mini in terms of greeblies and detail. It ended up being a scaled-up squad leader with a scepter. Literally, their leaders are just taller? Maybe I'll take another crack at his robes and add some trim to liven up the back of the mini. Big sigh.

The squad is where I took all my chances. Again, I painted a squad of these guys about 4 years ago, so the second chance brought many opportunities for improvement. I loved the purple glow, but I still think I can improve my technique. Tips appreciated. I'm not sure I have the heart in me to do a third squad. Going to try some Sicarians and other Ad Mech units instead.

A bit anxious about what to do to make my Next units stand out but mesh with this scheme:

• ⁠Sicarians can basically echo the black jumpsuit with metallic bits, but I feel like going with that will lack some pop. Maybe leaning into the purple energy on their blades and finding accent pieces to pop with yellow and green?

• ⁠Pteraxi are the same conundrum, but a wing vein with a green on yellow pattern might be fun. I intend to do the flamer squad. I can really amp up the muzzle burn with purple hues rather than make them glow to match.

• ⁠Dunecrawler, ironstrider, and robots: I still haven’t done any armor. I don’t want green tanks. I need a good primary color. Was thinking a brown would pull in the base colors, but drab armor is not very 40k, but I’m planning a smooth ivory for my knights. That would tie all the big boys together visually. I’ll have to think on that.

Regardless, no more AdMech for a bit! After painting a big batch like this, I am going to take a break and paint some one-off RPG figs and smaller squads with more painting variety and skill-tests. A batch of Harlequins with their diamond tights and trailing streamers would do me well.

Star Wars Legion - Clone Wars Core Set and Commander Rex

 After painting Rex with my son, he convinced me to get the core set (what a fool I am). The kit was good for a first offering for new players and new collectors. And I got to take Citadel Contrast for a spin to add another skill for my painting belt.

The models were decent. ObiWan and Clone Troopers were supplied in bags, basically clean except for mould lines.  Owing to their spindly bits, Grevious, two Droidekas, and the  B-1 Battle Droids were still on sprue. The plastic is definitely different from Games Workshop sprue. It was less solvable than GW plastic when using Testors and Tamiya plastic glue. Parts kept coming unwelded, but a little super glue put it right. Detail was tight and almost always movie/animation accurate, and the extra parts for Grevious even allowed for some simple conversions (see below for an extra surprise; you can blame my son for it). After assembling them, I realized the 28mm accurate scale is so much more fiddly than the 28mm heroics I'm used to.  Hands and guns are smaller.  Weapons are smaller too. But the accurate proportions make for great squads. In a crowd, they look like right even when base to base.

I was not interested in spending months painting these minis.  Especially since my son had lost interest in playing almost immediately after purchase. I was delighted to find Sorastro's painting guides for Legion.  He helped me get from prime to table-ready in less than a month. This was my first adventure with Citadel's Contrast paint, and the advice to thin with medium and how to handle flow was excellent.  His colors were spot on too. After spending the pandemic bemoaning my mistake, it was refreshing to go so fast from concept to finished product.
