Bosch dishwasher: can’t find leak

[dan2cv]

Hi everyone,

I am getting an E15 error code on my Bosch dishwasher.

I opened it up, dried everything out and ran it again – and the water (and the error) came back – so there’s definitely an issue.

But I can’t seem to work out where the leak is coming from.

The leak seems to happen towards the end of the cycle which suggests it’s when the water is draining out.

Also a couple of days ago, the dishwasher wasn’t draining, so I put some vinegar and baking soda in to unblock it.

I wonder if in fixing the blockage, I did some more damage and caused the leak.

Does anyone have any idea where the leak might be coming from and how I might fix it?

Thanks in advance,

Dan

Could you give the actual model number please. Begins with Enr lazer etched top of the s/steel inner door, can be difficult to see. Some had it written on a white label about half way down the side of the s/steel inner door. Really ancient ones it was top r/h/side at the top on a visible label more or less just by the work top lid.

Sorry for the delay. “The leak seems to happen towards the end of the cycle which suggests it’s when the water is draining out “- more likely due to the pressure of steam within the machine on the last rinse just before it pumps out and so: common leaks on common Bosch models of the last 10 years: the plastic based models (so the whole base where the filter is) with the remainder with top and sides in s/steel forming the tank. Very common that the plastic base warps relative to the s/steel on the r/h/side or the back so you take the r/h/s panel and look for dried / damp/wet crusty soap deposits = front to back it should be a straight line where the s/steel meets the plastic base, if the plastic base is bent outwards that is a common place for a leak over time or much more rarely very fast – silicon sealant does not repair it but a metal bar mod kit usually does from Bosch – not listed on the parts diagrams. Instant leaks the actual plastic sump warps and leaks directly down onto the under base very fast where the emergency flood protection float assembly is so you`d find out fast within 15 minutes- quite common that one and a complete pain to repair. These are the main causes of leaks on your typical SMS series of models other than a mouse attack – apparently the British Gov`t conducted a poll costing tax payers 30 million quid ( because they are all a bunch of hopeless idiots instead of getting the army up to strength for the final war that is on the horizon – presently we would run out of ammo within days – sling shots do not stop missiles or tanks) and the conclusion was that the mice thought the outlet hose is very tasty as “9 out of 10 mice said they prefered it” from the other hose from water fill chamber on the l/h/s that goes to the sump !! One other leaky point is the lower door seal especially prone if a wash blade gets jammed front to back angle – though doubt it is that but could be or the front cabinet seal. The plastic large nut thing that secures the l/h/side water resevoir to the s/steel tank is another but less common thing that gets loose you should check.

PS the water diverter can leak too but I only had that ever happen once.- and what a pain in the arse that was to replace.Reference part diagram number 0440.

Thanks Andy!!
Ok so i have taken off the side panels and i can definitely see there are some issues!
In the attached image I can see some build-up in the two areas circled in red. And I think there might also be some inside in the area circled green.
Any ideas what the issues are and what I need to do?
Thanks!!
