What to do if my Global-Tek GT-CR1/BU Dishwasher has no machine operation?
- R
  Russell BrownAug 12, 2025
  If your dishwasher isn't starting, here are several things to check: First, check the fuse or circuit breaker. The conveyor may be jammed, so clear any obstructions. If you're using the auto timer, reset or replace it. If equipped with a table limit switch, reset it. Also, reset the manual overload protector. Ensure the door is completely closed. The door interlock switch may be damaged and require replacement. The contactor for rack transport may need servicing. Finally, adjust the clearance between the clutch and sensor to 2-4mm.

  If a valve (excluding solenoid types) is leaking, it might be due to foreign material obstructing its operation. To fix this, shut off the supply line, unscrew and lift the bonnet from the valve body, clean the valve, and then reassemble it.
