Hi
I have a Bosch SGS56E02GB/35 that has been causing me greif for some time now.
I have the machine in the garage now with the top, side and bottom panels off. The base had quite a bit of water in it which I have cleared out.
The machine is 3rys old and I can’t afford to pay anyone to fix it.
I’m an electronics engineer so i’m not phased by it but I’d really appreciate some advice.
Where is the most likely place for the leak (if there is one) ? I’m going to try running some programs and see if I can see anything with a torch but if the leak is tiny, suppose this may be difficult ?
Strange beast these with the side of, is there anything I can clean out while it’s dismantled ?
Looks gunged up in a couple of places but this may be OK. Below a float switch (near the flood protect switch) there a two clear tubes, one looks orange and one looks black. Is this normal ?
Also at the top left of the water tank or whatever it is, there is a small patch of gunk ?
Is the control electronics known to suffer (dry joints/ loose relays etc) if it is, i’ll take it off and have a look at that too ?
Last but not least, one of the front panel buttons is missing from where I gave it a whack once, not very technical I know, but the best of us lose our temper at times. Can I get a replacement switch or switch assembly from here ?
Thanks for your advice, really appreciate it…..
Steve
Re: Bosch Flood protection activated.
hi
one of the more likley places is the inlet valve
run the machine for about 20 mins then :zap: UNPLUG THE MACHINE :zap: but leave the water connected, then remove the side panels and then look at the valve inside the machine for a small drip (easier to see from the right hand side of the machine with a bright torch or you can remove the valve from the rear then look at it).
as for the blockages the one in the pressure chamber is the one to clean along with the hose from pressure chamber to the sump. the one at the top left is not really needed
and is it the switch that is broken or just the button

Hi
You could watch the fill valve, especially where solenoid attaches to valve unit. The seam there seems to weep occasionally even with appliance off providing mains water to it is switched on; thus requiring valve unit replacement.
Power off before attempting any investigations :plug:
GregRe: Bosch Flood protection activated.
Thanks for the advice, only the button broke, the switch is still OK.
Looks like i’ll have to dismantle the front panel to refit the switch ?
as for the blockages the one in the pressure chamber is the one to clean along with the hose from pressure chamber to the sump. the one at the top left is not really needed
When you say clean the pressure chamber, how do I get inside it, do I have to remove the whole water/drain tank ? Is the pressure chamber the 2 part chamber directly below the float switch ?
Just out of interest, what is the buildup at the top left of the tank, it’s right at the top, above where the drain outlet connects ? Does this have anything to do with my sons costantly putting plates full of phillidelia in the thing 😕 ?
Had it running continuously now for 6 hours, no water appeared in the botton so weeping sounds spot on, i’ll take a close look at the inlet valve.
Can I buy parts via this site ?
Thanks again.
Re: Bosch Flood protection activated.
Keep it simple, Steve. Basic service procedure is to clean out the hose in the front left corner – it collects sludge. Follow it back to the side tank – the pressure chamber has the microswitch attatched to it. It will lift out for cleaning purposes. This will eliminate the possibility of water leaking from the fill system.
The machine is not a waste disposal unit – a certain degree of rinsing is always required, and this will avoid the deposits accumulating in the drain baffle. Quite harmless, don’t let it get worse.
Control panel buttons are available as a set – 419160, about £8 plus the VAT and stuff; the inlet valve if required is 167025, about £18.
You can order through spares@ukwhitegoods.co.uk .

Penguin45, you have me confused now….
Which part lifts out for cleaning, there are two parts with microswitches on them, the top part (263097 regulator water level) and the bottom assembly (480748 Pressure chamber) ?
I can’t see how either of these remove without taking the water tank off which is full of water at the moment.
Is the hose I need to clean 298556 and how do you remove these, pull, twist etc. Does the metal plate at the front / bottom of the machine need removing to get at the hose ?
Sorry for the questions but i’d rather just leave it than risk damaging something.
Cheers
Steve
Re: Bosch Flood protection activated.
Hi Steve
Remove ribbed hose 298556 and thoroughly clean, that is the front left hose Penguin is talking about. As for the top part that removes you correctly identified it as 263097, remove that and clean that and the bath it sits in.
Hope that clears that up 😀Greg

Probably best idea is to bite the bullet and call in an engineer in that case. No point having a D/W sitting there doing nowt 😉 .
Re: Bosch Flood protection activated.
Sorted it now, thanks everybody for their help.
After all this messing, the hose and the pressure valve were not really that bad…..anyway, clean as a whistle now.
The inlet valve looks OK, no drips but I think I have found the source of the problem. A small leak from the hose connection, this drips onto the outside case where a nice hole leads it into the machine…….
I don’t know if this is intentional but damm clever that it can detect a fault that is nothing to do with the machine. It’s now restored my faith in Bosch.
Once again, thanks very much for the advice, wifes now happy again.
Just need to order my new shiny buttons and were good as new. 😀
