Check Pump, Motor and Solenoid Valve (V1)
1. If coolant is not flowing, check to see if motor and valve V1 are getting 240VAC. Note: The 240VAC relay
(CR3) on PCB1 will not close until the first five (5) interlocks (STATUS) indicators are satisfied. (See
Startup Sequence
flowchart)
2. If motor, pump and valve all seem to be functioning and the flow is not sufficient, replace the pump and
motor assembly.
