TROUBLE SHOOTING
A. PUMP WILL NOT START
1. Check to ensure Power is switched on.
2. Check fuse (consult an electrician if in doubt).
3. If extension lead is fitted, check connections (consult an electrician if
in doubt).
4. Internal thermal cutout has not reset. Leave for 15 minutes and try again.
5. The Impeller may be jammed. Disconnect from the mains supply, remove
the bottom strainer and remove any objects that may be obstructing the
impeller. Replace the strainer and try again.
6. Float switch may be jammed against side wall or prevented from moving.
7. Water level too low - float switch in OFF position - Lift float to check
switch.
If the pump still fails to start, consult your CLARKE dealer for advice.
B. PUMP WILL START BUT NOT PUMP
1. Check to ensure strainer is not blocked - clean as necessary
2. Discharge tube clogged or obstructed - clear as necessary.
3. The head may be too great, i.e. you are trying to lift the water too great a
distance for the pump to cope with. (See specifications pages 10 ).
4. Impeller may be damaged - Consult your CLARKE dealer
C. PUMP WILL NOT STOP
1. Float switch may be prevented from moving to the fully down position.
2. Float switch may be faulty. Consult your CLARKE dealer for advice.
D. PUMP STOPS RUNNING
1. Thermal overload has operated. If this condition persists, investigate the
cause. Are you attempting to pump liquid which is too dense for the pump
(mud, slurry etc.), or too high a temperature.
2. Pump has run dry, or float switch has cut in.
3. A foreign object has jammed the impeller.
