Audio Desk Systeme - Vinyl Cleaner – Repair of Water Pump Failure

After the water pump of my beloved Vinyl Cleaner from Audio Desk Systeme stopped working I searched the web and found that I’m not the only one with this problem. But nowhere did I find a blog or post that would describe a repair procedure – other than to mail the machine back to Germany for an expensive repair.

If your machine is still under warranty you should of course send it back for warranty repair. But if your machine is out of warranty (like mine) and your only option is to spend lots of money to get it fixed, you might want to consider repairing it yourself.

The way the vinyl cleaner is designed does not allow any maintenance or replacement of any component located inside the machine without destroying something. The whole machine is glued together! Something I have not seen before to this extent – especially not on a high dollar item like this. Only the components in the upper compartment where the white cleaning rollers are located can be accessed thru the opening in the top cover.

To get started you need to separate the bottom PVC plate from the bottom of the tank. Both plates are glued together. I used a flat pry-bar to carefully separate the bottom plate without breaking it. Shining a flash light thru the water sight glass you can see the blue water pump thru the drain hole of the tank.

To get to the water pump you need to remove the bottom of the tank (or parts of it) which is glued to the recessed side walls.

Use a permanent marker to draw straight lines on the tank bottom – 5 mm inbound from the side walls. The PVC side walls are 5 mm thick. Try to cut slightly inside that line to not cut into the recessed side walls. I used a Dremel with a cut-off wheel.

Once the bottom of the tank is removed you have access to the water pump and all other internal components. To disconnect the pump wires from the main board you need to remove the front panel with on/off switch. Follow the pump cable from the tank and disconnect both wires from the terminal.

In my case it turned out that the pump actually did not fail - it was simply seized up. Once I rotated the little impeller by hand and hooked it up to the 24 V DC power supply in the sink it started to pump fine again.

In case you find your pump to be dead and need a replacement look for “Barwig Tauchpumpe Typ 3 24 V DC”. Price is around 18 EUR (appr. 20 USD) at or Unfortunately I was not able to find a supplier who would ship to the U.S.. You may need to be creative – or plan your next vacation in Germany ...

If you use aquarium grade silicone adhesive instead of strong PVC adhesive to put it all together you will be able to undo everything easier in case you need to access the inside of the machine again. 

Feel free to email me if you have questions or need pictures.


The issue with emptying the AD tank if not in use is the float can get stuck to the bottom and won’t budge. I have had that issue and was only remedied by leaving water in the tank for a period of time. 

What makes the pump stop working if it is immersed in water for a prolong period of time? Would be good to understand.
Update. I finally opened up my unit and the water pump is dead not seized. It now appears AD uses several models on water pumps. Mine is black and appears to be China made OEM pumps which are easily replaceable. The bottom like is the water pump is easy to replace once you have gotten into the innards of the unit. 
About to perform the surgery as soon as I get mine back (see sad story below). Can I get some pics that shows the "innards" so I don’t go wrong?
Have had the first generation of the AudioDesk cleaner for several years and it’s been a pretty bad experience.
When it worked, it was great but ...

After about a year the capstans rotating the record died. Sent of for repairs in Germany (I’m in Sweden), took about 2 months and cost about 5000 SEK (approx $500).
About 4 months ago the waterpump died, sent it off for repairs again, only to be informed last week (it took freakin 4 months!) that it is "too old to be repaired", but they offered to sell me a new (now the "Pro" model) for half the retail price (approx $1800). Don’t even know if I’ll get my old machine back.
Though it seems to be completely glued together, I thought I’d give it a try to replace the pump myself. Nothing to loose ...
Dealer said that through the years he had about 30% of the first generation AudioDesk cleaners returned for repairs.

Supposedly the current AudioDesk "Pro" model is more reliable, but I think I’m done with the Gläss Audiodesk as a company.

Lookng at Degritter now as a promising alternative.
You might find a similar replacement pump at an aquarium supply store. They may even have tools and solvents/ adhesives to work with the plastics more successfully.
