Allow motor to cool for 45 minutes. Retry.

Electrical outlet is damaged.

Reset building circuit breaker or replace fuse. Try
another outlet.

Check electric supply with volt meter. Meter must read
85 to 130V AC. If voltage is too high, do not plug sprayer
in until outlet is corrected.

Control board leads are improperly
fastened or improperly mated.

Replace any loose terminals. Make sure all leads and
harnesses are firmly connected.

Check pressure control harness connection on front
side of drive housing.

Clean control board terminals. Securely reconnect
leads.

Motor brushes are worn.

Check length of BOTH brushes (brushes do not wear
evenly on both sides of the motor). Brush length must
be 0.25 in. (6.4mm). If brushes are worn replace motor
