Thanks Peter for the info on the Inglis dishwasher. The “red button” I referred to, is on the back of the part (at the end of the dishwasher hoses) which hooks up to the faucet. When you push this button, water comes out of the bottom of the hook-up unit. I have no idea what its purpose is. If the problem is a blocked inlet filter, (how) can I unblock it? Or, if the problem is the solenoid coil on the valve, is it worth it to get it fixed? I think I would have to hire someone to do it. (The dishwasher was free.)
