Re: Bosch SGS3042GB/03 – timer sticking
How much water comes into the base? And are you sure the spray arms are turning properly?
Re: Bosch SGS3042GB/03 – timer sticking
This is going to sound stupid but how do I tell how much water comes in (to the base)? It all seems quite “wet” in there if I open the door mid cycle as in water is running off everything.
Again, how do I tell if the spray arms are turning – as I can’t open the door whilst its running to see. They turn freely enough by hand so I guess it’s water pressure that “spins” them?
Just been out out to check the spray arms for blockages – thinking if blocked then maybe they won’t spin and found one or two of the holes blocked by white, hard chalky scale. So will try another load now that they’re clear (stuck the garden hose up them and shook out all the bits). If that’s no better then I’ll investigate what feeds the spray arms.
Re: Bosch SGS3042GB/03 – timer sticking
Lol I would say that dislodged limescale is a probable cause for the not cleaning problem. As for the water fill level it should come just up to the rubber door seal at the front of the m/c. A good trick to see if the spray arms are working is to tie a rubber band/ string to the one side of the arm and see if it has moved when you open the door
Re: Bosch SGS3042GB/03 – timer sticking
Getting the hump with this thing now! Element now in and getting hot aok and cycle completes ok. BUT STILL STUFF IS DIRTY – brown residue in bottoms of mugs and a sticky “film” on most things. Bubble matrix is spotless and the little red float moves freely. I’ve had all the spray arms out, unclogged them and run the hose through them so they ARE clear. Don’t know what else to look for???
Re: Bosch SGS3042GB/03 – timer sticking
OK, on the water level issue first, once it has filled (usually 2-3 mins into the cycle) the water should be lapping the salt container threads and just below the salt cap. What you describe is a classic case of water starvation creating poor wash results. My guess is that there’s plenty of water in there but that the circulating pump is not doing its job. Through either being blocked with debris or the impellor blades have broken up through old age.
More surgery required I recon….. 😮
Re: Bosch SGS3042GB/03 – timer sticking
Sounds a good shout. Wife says that some mugs get clean others not. Presuming the pump motor is the one to the left of the element in my photos above? It runs nice and quite with no balance issues and seems to check out electrically. Oh well, in I go again to try and find the water route – to see if blocked and to try and get to have a look at the impeller. Any tips on the quickest/easiest route to the impeller? By that reckoning then I wonder if lack of water flow contributed to the element packing up in the first place! Cheers for that.
Re: Bosch SGS3042GB/03 – timer sticking
Well the wifes been washing up the old fashioned way for a while now! Seriously I’ve done my fair share with the dishwasher not working but am nearing the time when I’ll have to get a new one I think just to keep her quiet. Loathe to do so as the rest of the machine is in such good condition. I’ve had some replies suggesting water starvation and I’m heading towards that. Last chance for this machine I think! A few things I’ve done tried.
Started off with the timer not rotating and me thinking that was the issue but turned out to be the element not heating the water to then move the timer on.
Element was burnt through so have replaced that. Thinking maybe that water starvation might have contributed to that in the first place, as in not enough water flow over the element?
So with the element fixed everything is heating up and the timer goes through it’s full cycle. BUT the stuff is not getting clean! To be honest I noticed tonight that near the end of the cycle there is a “hot” smell in the kitchen. Gritty mugs with a “film” on other stuff.
I found the plastic matrix at the start of all this clogged solid with the little “float” at the top not moving. That is now 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} clean with the float moving freely.
Removing the little screw in the “well” exposes what I think is the impeller? This as you can see is clean. Rotating it with your finger and it doesn’t what I would call spin freely, should it? It almost feels as though its “sprung” as in you move it with your finger and it springs back! What drives this impeller?
Accessing the impeller:
The impeller:
Assuming this is the circulating pump motor? It runs fine when powered up, if I stick my finger in via the “well” it turns the motor and vice versa – nothing feels blocked and I can feel that the “blades” are clean etc.
Turning the motor:
Feeling the pump “blades”:
One last thing, not sure if, when I put the machine back together that I put the “3 pronged” piece that feeds the spray bar up the right way? I have by the way cleaned all the spray bar components thoroughly:
Many thanks for any help.
Re: Bosch SGS3042GB/03 – timer sticking
FIXED! And cleaning like new! A learning curve for me I’ll admit. I ended up investigating the water starvation and found the “grey pipe on the left” 90{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} blocked with scale – we live in a hard water area. Happy wife, so much so she let me go and buy a TomTom with the money I saved!
The “grey pipe on the left” – behind the front panel at base:
Also stripped the plastic assembly that feeds the above pipe. Cleaned everything by dosing with bicarbonate of soda then adding a good slug of vinegar, nice and gentle on the plastic, that and an old toothbrush! Also used a bit of Limelite on the real stubborn bits.
Re: Bosch SGS3042GB/03 – timer sticking
I have to thank you, you are certainly worth buying a few beers for!
The past week my old Bosch SGS3042GB/03 had been playing up. I could not definitely say the arms were rotating or not, but was not convinced. I was starting to look at buying a circulation pump at around £160, but as this machine was bought from a friend 3 years ago (and not knowing how old it is) I was probably going to buy another (cheaper) machine. During the week I had cleaned everything that I could easily take off (but I could not check the pump electrically).
Having Googled the problem I came across this thread. It saved me soo much time by not stripping the whole machine as you have done. I went straight to that pipe after turning the machine on to its back…it was blocked solid. I cleaned it out and replaced it. Chucked a descaler in to the machine earlier today and my first load after is all shiny and clean 😀
Having seen your diagrams and having now fixed my own I am confident that in the coming few weeks I can service it properly; strip it down and clean it thoroughly. I will also replace the detergent tray as that does not stay closed anymore.
Again, many thanks.

Orange Peel, could be expensive buying those beers as my preferred tipple is a New Zealand beer called Speights Gold Medal! Seriously though, glad it all worked out for you. Good feeling when it all works out!
Re: Bosch SGS3042GB/03 – timer sticking
Can anyone point me to where to get the combined mains inlet and suppression filter as mines a tad burnt! I CAN get just the suppressor but can’t seem to find the actual assembly with the hinged lid etc that the wires go into. Many thanks.

Only direct from Bosch though it is showing not available for some reason right now. Click HERE for further info direct from the horses mouth as it were. 😉
Re: Bosch SGS3042GB/03 – timer sticking
Well, I got a new mains inlet and suppression filter all good and fitted. One thing I noted though which I’m thinking is maybe a bit odd – bearing in mind I’ve had this thing apart before. What I believe is the steam vent pipe – comes out of the rhs side then loops and goes into the casing at the back behind the instantaneous water heater – but it doesn’t go “anywhere” just exits into the space underneath everything so I guess the steam must just condensate in the base of the unit? Is this right? I’ve read on some models this goes to the drain side:
The corrugated pipe coming in from the right:
Thanks
Re: Bosch SGS3042GB/03 – timer sticking
It is meant to do that. It is just an air vent pipe. It’s location is exactly as it should be. Leave we’ll alone.

Cheers. All working now. You say it’s an air vent pipe…….deffo then NOT a steam exit pipe?
Look in the second picture and you’ll see the pipe in question resting on a vertical plastic section – that is in fact hollow and exits on the floor below the washer. The corrugated pipe fits in it perfect. I was wondering then if that’s where this pipe is supposed to sit?
