Hi I pulled the machine out and tilted it because the tap indicator light came on. It now seems to be working again but not sure for how long. I noticed there is a lot of grease/gunk in the pressure chamber. How do I remove all this without having to dismantle the whole thing? I am running a 70 degree wash but it does not seem to be shifting? I also noticed when I pulled the dishwasher out, the pressure chamber was full of water. Is this normal?
