Jobo ATL-2 rebuilding project

[Kino]

Random bit of information: This is a direct replacement for the water circulating pump on an ALT 2200/2300:

BOSCH 0392020024 Original Equipment Electric Auxiliary Engine Water Pump - Compatible with Select Volkswagen Beetle, Golf, Passat

This can still be found in auto parts dealer inventories for now and currently runs about $60 USD.

Oh and BTW, this part is now $90 to $250 in the USA when you can find it...

You mean doing the bleach-fix outside the machine? Why this? Even if every use I do a cleaning cycle?
Ps the water pump is quite cheap in Italy/europe, about 26/30€ in some places

Not a surprise for obvious reasons.

How much complicate is to unmount the jobo atl2 for a good clean and maybe how difficult is changing the silicone chem pipes? thanks in advance

My chem pipes are sealed-in with silicone and are hard to trace without taking the head apart. I refused to dismantle the head unless it is absolutely necessary.

To clean these pipes, I attached a bit of microfiber cloth to the end of a moderately flexible bit of insulated copper wire and pushed it up into the discharge port of each chemical bottle. I then poured a citric acid mixture down to fill the tube and let it soak before flushing with several liters of water.

You can even swab the length of the pipe with the microfiber contraption IF you don't get too aggressive and are patient.

Seems to have done the job and cleared the tubes.

Citric acid is great for lime. Slightly warm the solution too.

I worked in an analytical chemistry laboratory for several years we used formic acid to clean steam generators. Nasty stuff and expensive, worked great.

Bar keeper's friend works well too.

Hi everyone, so they give me this atl2 and from the videos they sent before picking it up machine was turning on good. Now I started cleaning it and wanted to reset some programs… now the machine gives me 30.00 error with 3 blinking. I can check the temperature, moving the arm but nothing else.
Any suggestions?
Thanks
