Bosch washer/dryer inlet valve wiring

[Ak27]

Iv replaced my 3way inlet solenoid valve of my bosch wvd24520gb washer dryer. Since replacing the inlet valve Iv had a problem with it in drying mode. The drum fills with water and shows an error code of f18. Iv checked the drainage pipes and pumps, which is all ok.
I think Iv replaced the wiring on the inlet valve incorrectly, so it’s allowing loads of water into the drum when drying.

Can anyone advise me of the correct wiring?

The wires I have are 2 blues, 2 reds, 1 brown, 1 brown/blue and 3 solenoids.

Would really appreciate you helps

Thanks

Re: Bosch washer/dryer inlet valve wiring

I reckon you’ve wired it correctly. The problem more likely due to the fact that the valve is not sealing off correctly on the dryer side. To check that (with the power disconnected) simply remove the dryer/ condenser hose at the valve end. I think you will find it is dripping, if so try tapping the valve gently and it may well stop with any luck? Then try it a few times by switching power on and off just to be sure it is cured otherwise that new valve you bought is faulty.

Removed the hose to check the valve and it seems ok as no leaks. With a multi meter I have also checked voltage across the terminals. 240v across the condenser valve when in dry mode, nothing on the other 2. Also checked resistance with wires removed and got 3.6 ohms across the first 2 valves (both black) 4.2 ohms across the condenser valve (white). I presume the colour of the valves is code for resistance values?

This time the machine stopped with a f17 code?

Re: Bosch washer/dryer inlet valve wiring

I take it back! Think your right. Taken the hose off again it it is trickling water. So where does this water go? Surely I should have noticed a build up of water in the drum? Or does it go into the condenser then drain from there? But if that’s the case why do I get so much in the drum after drying and getting a code.

Not questioning your diagnosis, I just like to get me head round these things

Thanks for your help

The trickling water goes to the condenser then on into the drum. If a light tap doesn’t stop it from trickling then get another new valve to sort it!

Gave it a tap last night and think I made it worse! Woke up this morning to water all over my kitchen floor. Going to order a new valve ASAP.

Thanks for your help
