Hello Peter. You would have to make sure you are using the right one by checking it on a spare site like Ransomspares. If there are different once fitted to different models you will be told to enter the product number or serial number to check which one you need. Pressure switches are pretty reliable but the new ones are a sort of magnet inside a coil and different to how they always used to be manufactured and designed. I don't know yet whether they are more or less reliable. If you are sure that the error code means that the water hasn't pumped away and there is definitely no blockage then the pressure switch could be the problem though you would have to be prepared for it to not be as it could also potentially be connection problems or even potentially a fault on the PCB.

Thanks Andy , yes I had a look at the pressure switch and hose and cylinder at the end . I heard it can get blocked stopping the air pressure . But it's as clean as a whistle . So It must be the switch itself . Are all Logik pressure switches the same type , Thamks Andy

Hello Peter. Yes it still sounds like the same issue that I described in my first reply. If it is telling you that is failing to drain the water but you can clearly see that all the water is being pumped away then the fault lies in the system that detects when the water has gone. That's the pressure system that I mentioned.

Hi Andy thanks for the reply it seems to be stuck in pump out mode , I filled it with water today , put it on Drain and it emptied it no problem then up came E21 . Would not work on any other setting but sound like still in pump mode ???
