Hello. Got this code about a month ago on startup. We found out that if we only ran the 45 degress quick cycle the dishwasher would still run, but this also now get the same error code.
I contacted Bosch but they say it’s not the Heat Exchanger Valve that is often quoted as being the culprit, as our model does not have this.
Has anyone had any experience of this or able to advise on what we can do, other than a very expensive Bosch engineer visit!
The dishwasher is less than 3 years old and has only had light use, so we’re rather gutted.
thanks very muchwell when i looked it up your machine has the valve

Hi Dave
thanks very much for replying to quickly. In your experience is this the source of this error given how the fault developed, or is it not that clear cut unfortunately? Odd that Bosch told me contrary information to this.
thanks again
AdamHi Dave, thanks for that. I’m not an expert but do have a multi-meter so will take the back off and see if I can check it. Hopefully it’s relatively straight forward and this is the cause of our problem.
thanks again
Adampic is not big enough to see but to remove wire there is normally a plastic latch that has to be eased out the way to withdraw the plug

I’ve tried to unlatch it but it feels very stiff and that if I do it any harder it might break; not how I’d expect such a connector to feel. unf the site only allows tiny photos, so I had to reduce it a crazy amount of times to fit! I guess I might have to pay the extortionate Bosch engineers cost.
I’ve posted it on facebook, hoping this link will work to that:

lets do it a different way
below is a pic of the valve with the latch to remove plug arrowed. you need to pull the latch back carefully and gently remove the plug

Hi Dave that was ideal thanks. Once we were able to lift the dishwasher above the ground enough to see under, I could see a hook holding the clip in place and so could undo it.
My problem is now that my multimeter pins can’t reach the connections inside the valve, as there is literally no space in there. It being so low down and facing downwards only makes it worse; it does feel like they are not designed to be worked on! However, I have seen a video so know how to remove the above item. Our problem now is that the plastic tank on this side of the item is still full of water, so if we remove the valve it looks like we’ll get water all over the kitchen floor and into the base of the dishwasher. Do you know if there is a way to remove all the water first, or do we have to try and catch it as best we can?
thanks very much Adamthis is the tank I mean, I’m pointing at the water level:

thankscant think of anyway to empty tank and if its failed you will have to do it anyway. lots of towel is normally the answer and with care you can start and stop flow
As for testing i think the connecter on the valve can be carefully prised out of the way to access the pins on the coilDave
