Hi everybody. I apologise for re-posting this, but the trail seems to have gone cold because (probably as a newcomer) I couldn’t post a picture of my dishwasher on Saturday afternoon.
When the wash should be starting the pump is making a very laboured noise.
The flightless One and Nomad kindly talked me through getting access to the pressure vessel, because at the point the noise starts there is hardly any water in the machine, hence there must be trouble getting it to fill properly.
The vessel on mine looks pretty clean to be honest, and I don’t know how hard I can pull on it to remove it to clean it out. Also the float mechanism is in the way.
I currently have the top and both sides off and Mrs OldCodger asking me what I’m going to do with it 😳
Again, sorry for re-posting this, but I am stuck for what to do next. Having had all 4 of our major appliances fail in the last 3 months (and none of them ancient) I am desperate to find a diy solution if possible.Re: BOSCH SGS5302GB07 MOTOR NOISE
The “trail went cold” because you signally failed to follow the advice you were given. The comment that you didn’t know where the salt cap was rather finished our efforts to assist you.
If you wish to have one last go, drain the machine, pull the plug, then remove the water matrix. It unclips at the top left corner, then lifts away. Put a towel down, there will be water……… With that disconnected, you can then lift the pressure switch chamber up and off, taking the red flood protection rod with you. This gives you enough room to pull out the transfer hose as well. Clean everything thoroughly with hot water, re-assemble and check the level when it fills. The salt cap is on the floor of the cavity, next to the filters. Water level should be half way up after the fill sequence.
If the circulation motor still sounds strange after this, you will have to remove it and find out what’s going on inside. Access involves removing the entire stainless cavity off the machine and I’d rather not go there yet.

Re: BOSCH SGS5302GB07 MOTOR NOISE
I am in your hands here and I am very grateful for the help. On Saturday what I was trying to say was that the vessel that in your picture that was full of goo, on mine looks pretty clean, but there was a load of goo at the top of the matrix, which you said was irrelevant to the problem. I tried to post a picture but as a newcomer I don’t think I’m allowed, so the post got very messy, and I apologise for that.
I had at that stage already done as you are suggesting, i.e put a towel down and unplugged the matrix, but it was at that point I was not sure how much pressure I could put on the pressure switch assembly to pull it all out to get at the hose and clean it. So I will give it some more pressure now that I know it is supposed to come out by pulling it. I will let you know. Thank you.Re: BOSCH SGS5302GB07 MOTOR NOISE
I have removed the pressure switch chamber and it was as clean as a whistle. Whilst the hose was disconnected from it I put a small brush down that as well to check it was clear, but I could see down it that as far as the eye could see, it was notably clean. I put it back together again and switched on, and the noise is still there unfortunately.
Re: BOSCH SGS5302GB07 MOTOR NOISE
I realise now why you must have thought I was a complete numpty asking where the salt cap was. I have always known it as the salt reservoir, and I was assuming “salt cap” was some component that was in the picture P45 posted, i.e some part of the filling assembly. 😳
Anyway, I have checked and the salt cap/reservoir is full of water. However, I have started and pumped out the machine about a dozen times now, and I am sure that the noise is getting quieter, but it’s clearly still not right.
Time for the white flag?Re: BOSCH SGS5302GB07 MOTOR NOISE
I suppose there must come a point where you have to say “Enough”. If you are absolutely sure that the pipework and chambers are clear, logically, the machine should fill with an appropriate amount of water to allow full circulation. If you are not getting full circulation, accompanied with the noise, there must be a problem with the circulation pump.
This is where it gets complicated….. Access to the motor involves removing the stainless cavity from the machine. Screw in each lower corner, screws in the sump, door panel off – they all have to go. As a professional repairer, the strip/build is likely to take the best part of two hours, plus what is needed to actually repair the machine.
I appreciate that you’ve had a run of bad luck, but from here on it gets very complicated. Forum Rules dictate that we can’t walk you through it absolutely step by step, so time for some help might be the best way forward if you wish to keep the applaince running. If you are an “old codger”, you do have the one thing that we repairers don’t have on your side – time. Time is money as a professional……. It’s really pretty straightforward if the job is approached logically, although diagrams, pics and patience (lots) are required.
Not really much more I can tell you as things curently stand, so I’ll wish you luck.

Re: BOSCH SGS5302GB07 MOTOR NOISE
OK, thanks for your honesty and advice. The machine is about 6 years old (I think), and we replaced the main circuit board about 1 year ago as the engineer told us that in his opinion it is a well made machine worth keeping. Always the owner’s decision of course, and I suppose logically it’s had a good run! I reckon I will have a go, on the basis that the worse that can happen is I end up buying a new one anyway.
They say things go in threes: An AEG frost free upright freezer, 3 years old, scrapped in December because compressor packed up. Aeg Lavamat washing machine sometimes “hanging” mid program, and other times working fine. And just this week a John Lewis tumble dryer, 2 months out of warranty (38 months old) on off push switch not activating the programme.

That same engineer most likely would offer you help in resolving your problem quickly and cheaply I’m sure. How about giving him a bell or indeed calling one of the local recommended engineers by checking out own repairs@ facility? 😀
Re: BOSCH SGS5302GB07 MOTOR NOISE
I spoke to an engineer earlier today on the phone, and on the assumption that he would need to get at the motor (stainless steel cavity out etc.) then he said around £140 – £150 as a ball park. This assumes some kind of motor repair, not a replacement. This is half way towards a new machine, so is it worth it? Is a £300 machine any good?
