Bosch SGS5362GB/01 not heating water – PICTURES ADDED

[HairyBoy]

Hi,

our Bosch SGS5362GB/01 has started acting eratically and not cleaning very well and I am hoping you guys can help.

Upon a little investigation it appeared there were some small pieces of plastic packaging stuck in the top spinner which I have now removed (not sure if somemore of this may be lodged elselwhere ?)

Also, the water is no longer getting hot and the wash cycles have gone out to 180 minutes which is really long.

I read on here that there maybe a shorted dry solder connection on a board in the Control Module so I had the control module out last night and it appeared there was a blown connection which I carefully re-soldered.

Now the water still isn’t heating beyond tepid, selecting an intensive 70C cycle lists just 20mins but sticks at 1 minute remaining and never ends whilst a 55-65C cycle reports 180 minutes ?

I need some help in isolating whether a water heating unit (element ?) or the control module is at fault before spending money on the wrong spare part ? Or could it be a blockage somewhere caused by these smallish pieces of plastic packaging ?

Removed bottom front panel to check lower hose for blocking just incase. hose looks to be clear and water levels appear fine when opening mid-cycle. Just wanted to rule this out as seen some other posts suggesting low water levels, blocked hose could cause dishwasher not to heat water.

Any pointers on checking whether the control module or the water heater is the problem ?

Ok,

so sides off and looking at the left hand side all the chambers look clear so no sludge or anything present. Hopefully this image works:

On the right hand side bottom, I think I have correctly identified the heater and have checked the resistance across the two points identified with red circles (I disconnected 1 connector first). Hopefully this image works:

If I have measured across the correct terminals (someone please confirm) the resistance is 24ohms so I think this indicates the heater is fine ?

Am I right in thinking it must be the control module then ?

Sent the control module today to QER off of Ebay for repair

Assuming they can repair the module do ask them what they think could have damaged the blown connection.

Its rare for a module to blow on its own accord. There are a number or factors which could have caused the module to fail.

The last thing you want to do is plug in the repaired board and it go pop again.

Thanks Tim, I will ask QER what may have caused the module to blow.

Thanks for the advice.

Received the repaired module back from QER and installed it.

Now done 2 washes and the dishwasher has worked perfectly. Lets hope this is a permament fix.
