9.2 Motor starts, but makes noise.
Possible Cause
1. Debris lodged in the pump housing.
2. The motor fan cover has been dented or has collected debris.
3. The motor is rotating the in the wrong direction (only occurs when motor is first
installed or replaced).
Solution
1. Turn the power off to the machine at the circuit breaker in the wall mounted
electrical enclosure and remove the motor assembly (see sections 7.1 & 8.1). Be
sure that the heater cover in the back wall of the wash tank is secure with no
gaps around the edges that will allow foreign objects to enter the pump suction
manifold (see section 8.2).
2. Turn off the power to the machine at the circuit breaker in the wall mounted
electrical enclosure and remove the motor fan cover. Straighten the cover or
replace it if the cover is damaged, clean the debris and install the cover back
onto the motor.
3. 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 qualified electrician).
