Electrical Troubleshooting

If your machine will not start, follow these guidelines to help determine a cause and find a possible solution.

 

 

Possible Cause

Corrective Action

 

 

 

 

 

 

 

 

 

Control Settings

STEP 1: Ensure that the on-off toggle switch is in the “ON” position and that the

 

 

 

Pressure Control Knob is fully counterclockwise (maximum pressure). Also check that

 

 

 

the unit is plugged in.

 

 

 

Fuse

STEP 2: Test the fuse for continuity or replace with a new fuse. If fuse is good, go to

 

 

 

Step 3.

 

 

 

STEP 3: Remove screws and lower the pressure control assembly and check to see if

 

 

 

the red power light on the board is lit. If the light is “OFF,” proceed to Step 4. If the

 

 

 

light is “ON,” go to Step 7.

 

 

 

Power Source

STEP 4: Use a multimeter to check for 110 volts VAC across the L1 AND L2 terminals

 

 

 

on the board. If there is no voltage at these leads, there is no power to the unit.

 

 

 

Check power source (outlet, breakers, extension cord and power cord). If there is

 

 

 

voltage on L1 and L2, go to Step 5.

 

 

 

Thermal Overload

STEP 5: Disconnect the two red motor leads (S1 and S2) and test for continuity

 

 

 

between the two leads. Continuity shows that the motor's thermal coupler has not

 

 

 

tripped. No continuity means that the thermal coupler has opened due to excessive

 

 

 

motor heat. If the motor is still hot to touch, allow to cool and retest. If the motor is

 

 

 

cool and there is no continuity on the red leads, contact the nearest Campbell

 

 

 

Hausfeld Service Center to repair or replace the thermal coupler.

 

 

 

Pressure Control Assembly

STEP 6: If all checks out fine in Steps 1 through 5 and the red light is still out, the

 

 

(Board)

pressure control assembly is defective and must be replaced.

 

 

Motor

STEP 7: Remove motor Brush Covers. Turn unit on with Pressure Control Knob fully

 

 

 

 

clockwise to max. pressure position. Check for DC voltage across both brush

 

 

 

terminals. If you have greater than 80 VDC turn unit off and unplug. Ensure that the

 

 

 

brushes are evenly worn and make solid contact with motor commutator. Replace

 

 

 

the brushes if they are less than 3/8" long. If the brushes are okay, replace the

 

 

 

motor. If you do not have DC voltage at the brush terminals go to Step 8.

 

 

 

Sensor

STEP 8: If the redlight is "ON", the power source, fuse, on/off switch and thermal

 

 

 

coupler are okay. Plug another sensor into board. If the unit starts, the sensor was

 

 

 

faulty and must be replace. When a replacement sensor is not available, use a

 

 

 

multimeter to test the resistance between the BLACK and RED wires on the sensor

 

 

 

lead. The resistance should be approximately 1.5 - 3.5 kohms. A faulty sensor usually

 

 

 

reads no continuity (open). Conduct the Zero calibration procedure. If unit cannot be

 

 

 

zero calibrated, that ensures sensor is bad. If sensor check is good, go to Step 9.

 

Pressure Control Knob (Potentiometer)

STEP 9: With the machine still "OFF", remove the potentiometer lead from the board and read the resistance between the red and black wires. This must be 8 - 12 kohms. If outside this range, replace the potentiometer. NOTE: A bad POT usually show no continuity (open).

Pressure Control Assembly

STEP 10: If you do not have DC voltage at the motor brushes and all components

(Board)

check good in Steps 8 and 9, the Pressure Control Assembly needs to be replaced.
