CHAPTER 5 – MAINTENANCE AND TROUBLESHOOTING
WARNING
DANGER
Electric shock risk
Under normal conditions CMX electropumps do not need any type of maintenance. In order to avoid
possible failures, it is advisable to periodically c heck the pressure supplied and current absorption.
A decrease in pressure is a symptom of wear.
An increase in current absorption is a sign of abnormal mechanical friction in the pump and/ or motor.
If the electropump is not going to be used for long periods of time it should be emptied completely,
rinsed with cl ean water and put in a dry place.
PROBLEM
The electropump does not
pump water, the motor
does not run
The motor runs but the
electropump does not
pump liquid
Make sure the machine is disconnec ted from electric
power supply, before performing servicing operation
POSSIBLE CAUSE
1) No power
2) Motor protection tripped
3) Defective condenser
4) Shaft blocked
1) The pump is sucking air
2) Wrong rotation direction

REMEDY
1) Verify the presence of voltage
2) Verify the cause and reset the
switch. If the
thermal circuit breaker has tripped
wait for the
system to cool down
3) Replace the defective condenser
4) Verify the cause and unblock the
electropump
1) a) Make sure that the joints are
airtight.
b) Check that the level of liquid has
not lowered
c) Check that the foot valve is
airtight and is not blocked
2) Reset the direction of rotation
