TROUBLE SHOOTING
A. PUMP WILL NOT START
1.
Manual type (i.e. without float switch)
1.1 Check to ensure Power is switched on.
1.2 Check fuse (consult an electrician if in doubt).
1.3 If extension lead is fitted, check connections (consult an electrician if in
doubt).
1.4 Internal thermal cutout has not reset. Leave for 5 minutes and try again.
1.5 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.
If the pump still fails to start, consult your CLARKE dealer for advice.
2.
Automatic Type (with float switch)
2.1 Check all above.
2.2 Float switch may be jammed against side wall, or prevented from moving.
2.3 Water level too low - float switch in OFF position - Lift float to check switch.
B. PUMP WILL START BUT NOT PUMP
1.
Water level too low - below the minimum suction level (Manual type).
2.
Check to ensure strainer is not blocked.
3.
Discharge tube clogged or obstructed.
4.
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 9 -10 ).
5.
Air bubble in the pump, produced during the plunge. Plunge the pump again,
at an angle, and shake it whilst lowering to remove any air trapped in the system.

Impeller may be damaged - Consult your CLARKE dealer
C. AUTOMATIC 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.

Thermal overload has operated. If this condition persists, investigate the cause.
Are you attempting to pump liquid which is too heavy for the pump (mud, slurry
etc.)
2.
Pump has run dry, or float switch has cut in.
3.
A foreign object has jammed the impeller.
