Customer complaining of not spinning correctly. Brushes worn so I changed them. Put unit on spin but only rotated twice and sat there pumping out. No further action. Am I missing anything obvious? Checked pressure switch/chamber and connections. Any advice for me??
Check connections to motor tacho, wires brake at tacho, just check the resistance, it should be about 40 ohms i think. also check motor rotates both ways on wash.
The one thing I did notice was it rotates one direction, I hear the click as if it’s going too rotate again but nothing happens. So it does appear to be only rotating one direction. So is it.. A. Tacho
B. Motor
C. PCB
D. Heater
E. None of the above.
Won’t get back to this unit til Monday as they’re away. So going back fully armed!! Thanks for the replys lads..
