9.3 Motor starts, but no water flows in the wash tank.

Possible Cause

1. The pump impeller is broken or not connected to the motor shaft.

2. The motor is rotating the in the wrong direction (only occurs when motor is first

installed or replaced).

Solution

1. Turn off the power to the machine at the circuit breaker in the wall mounted

electrical enclosure and remove the motor assembly (see sections 7.1 & 8.1).

2. Turn off the power to the machine at the circuit breaker in the wall mounted

electrical enclosure and change the wiring connection for the motor (This must
be done by a certified electrician).

9.4 The control circuit fuse “blows” when the power is turned on.

Possible Cause

1. There is a short circuit in the chemical dispensing pump (not all machines have a

chemical dispensing pump).

2. The coil in the contactor is drawing too much current.

Solution

1. Disconnect the cable on the back of the chemical dispenser and try a new fuse.

If the fuse does not “blow” then have the chemical dispenser checked by a
qualified service person.

2. Turn off the power to the machine at the circuit breaker in the wall mounted

electrical enclosure and replace the contactor.

9.5 The lights indicate that the tank is empty when it is actually

full.

Possible Cause

1. The sensor is coated with debris.

2. The wire connected to the sensor is loose or broken.
