What to do if hot water does not enter the tub in wash cycle of my Dexter Laundry T-650?

If hot water isn't entering the tub during the wash cycle of your Dexter Laundry Washer, start by checking the water valve coil for continuity at the terminals and replace it if there's no continuity. Also, check for 24 VAC (50 Hz) power from the main relay PCB. Inspect the water inlet screens for blockage and clean them if necessary. Ensure that the water supply is turned on and operating correctly. Finally, check the black and white wire at the Molex plug on the main PCB controller P21 connection and at the PCB relay board P20 connection, and examine the pressure switch continuity between terminal contacts. If no continuity, check the pressure switch hose for obstruction. If the hose is okay then change the pressure switch.
