Bosch SGS43E02 pump runs forever – no water in base…

[Wibbly]

From yesterday it seemed to stop pumping out all water and left the pump running continuously. Now, after a reset, it seems to drain (more slowly – I’m not sure??) and the pump still continues to run once the display has counted to 0.

Thinking this could be the drain hose partially blocked or the bottom of the machine filled with water, I took the sides off – no water I can see in the base (very clean actually), and nothing looks blocked. I had the machine actually lying on its front for a while, so anything in the base should have drained out anyway.

The motor that runs at the end (with minutes to run down to zero) is quite quiet.

Any ideas?

Hi
With the appliance un plugged I would be removing front plinth to gain access to ribbed translucent hose that goes from pressure unit on l/h side to the sump.
When found, remove and clean thoroughly.

Report back if no change 😀

Just to add, its worth checking the float hasn’t been chewed to a pulp also and activating flood microwitch 😉

Thanks greg

Sorry to have to ask –

– is the front plinth supposed to come off by releasing the two screws on what look like end thin plastic caps in either side of the plinth? It didn’t seem obvious to me how the planth is removed…

– also where am I looking for the float? What I’d guess was the flood microswith and it’s actuator seemed free (an unactivated) whilst I had the side off.

Yes

Yes, lid off then l/h panel.Float is front left, will be obvious if Jerry has been there 😆

Behind the front valence is only another panel with a hole in its center and some arrows round it. Looks like it can have a special tool inserted into it?!

Anyway, behind LH side panel the float looks fine and there is a translucent hose part of which is revealed (bottom right). I think this is the hose you mean. It had had some (pretty clean) water in it. I also removed what seems to be some kind of guard over an impeller at the bottom of the machine (inside where the water drains from the dish cleaning area). It was clean in there too.

I then decided to run the machine on a rince cycle with the sides off. Penty of water flowing freely as it appears it probably should. I cut the cycle short (reset) and just as it ended (pump still stuck running) I opened the door. It appears the mode it’s stuck in is actually trying to pump water through the rotating arm. It was clearly trying to eject a little water left in the system – it maybe isn’t the main “drain water” mode in which it’s left at the end of the cycle… (hence the quieter than normal sound perhaps). Is this normal operation?

Does help point out where the problem may be?

If you look left and right there are some torx 20 screws, remove them and that front should pull off. It will come off easier if left and right panels are off 😉

There is a metal guard secured by torx screws (behind the removed front valence). Attached to it a cabling support that goes to the door. behind the panel is some sound proofing and behind that and VERY difficult to get to still is the hose. But see my above edit – that hose may be nothing to do with the problem?

I still think its a crud blockage either in that hose or metering unit area.

Thanks for your help. Is the metering area the area behind the left side panel?

[If I go down the engineer route, what makes them ‘approved’ by this site, please?] Edit – Ah it’s ok I just found the link that explains all on this

Did that. And for the record had a good experience. Weirdly, the machine worked when the guy arrived, but he charged a minimum amount and was a pleasure to deal with 🙂

I wouldn’t have expected anything less from the guys on here :tup:
Thanks for taking the time to praise the engineer who visited, it is appreciated.
