Having read through some of the posts.Is it or is it not ? possible to change the water distributor valve on this m/c . without taking the tub off.you can take out the module and the heat pump on this machine if that makes it any easy`er .
In short , yes you can. Its a bit fiddly but can be done. The hardest thing is getting the distributor back on and the trick is to put the seal onto the sump first , making sure you put a touch of washing up liquid on the seal before offering it up. Its also important to make sure the distributor is fully pushed home on all sides before twisting it back on.
