This “TROUBLESHOOTING” information is intended to guide in the general determination of pump problems and their solutions. Each manufacturer normally provides a description of warranty conditions. Some pump warranties are immediately voided if the unit is disassembled. Be sure to thoroughly read the owner's manual and warranty. BILGE PUMP DOES NOT RUN.
PUMP (115 VOLTS) DOES NOT RUN.
- Wire connections:
- Check wire connection integrity
- Check that connections are not corroded.
- A slight pull on each wire will indicate if wires are still connected.
- Check to sure no wire joints are hanging down into the water
- Blown fuse:
- Verify correct fuse size, (it is printed on the side of the bilge pump.
- If fuse size is correct, check impeller through the inlet opening to be sure it is not jammed or stuck with debris.
PUMP ONLY RUNS FOR A FEW SECONDS:
- Electrical connection:
- Check electric receptacle for power.
- Check fuse and or circuit breaker.
- Is the receptacle a three prong grounded outlet in good condition?
- Is the plug making good contact in the receptacle?
REPEATED BLOWN FUSE.
- Insufficient water:
- The automatic system tests for water approximately every few minutes.
- If the water level detected is only about 3/4", the pump will shut off after a few seconds.
- Every few minutes thereafter, it will automatically check the water level and will only continue pumping if sufficient water is present.
- Clogged strainer or jammed impeller.
- Disconnect pump from the power source and remove strainer
- Remove debris from the strainer and surrounding area.
- Remove any debris from the impeller.
- Blocked discharge line:
- Disconnect pump from the power source and remove blockage from pipes/hoses and discharge port.
PUMP RUNS BUT DOES NOT PUMP WATER.
- Fuse rating or clogged impeller:
- Re-check fuse to verify compliance to pump specifications.
- Also examine impeller area & clean any obstructions.
PUMP SHAFT CORRODED.
- Airlocking / cavitating:
- Inspect & reposition hose for short vertical discharge.
- Install pump below water line to insure sufficient water flow.
- Do not install a check valve on the pump discharge line.
- Pump strainer & impeller area clogged with debris:
- Disconnect pump & clean outside of strainer
- Clean debris around impeller, & reattach & re-hook wiring
- Wrong Polarity (DC Pumps Only):
- Switch wiring for correct polarity
PUMP STAYS ON AFTER WATER IS PUMPED OUT.
- Electrolysis, cracked housing:
- Inspect pump housing for cracks which can cause leakage into motor cavity causing corrosion.
- Possible errant current running through wiring causing corrosion.
- Wire connections may be incorrect
- Automatic pumps may have faulty circuit
- Possible electrical short
PUMP IMPELLER SPINS BACKWARDS.
- Hose clamp fastened too tightly.
- Suggest using plastic style hose clamp
- Do not use pvc hose
WIRES OVERHEATED AND MELTED INSULATION.
- Switch wiring for correct polarity (dc pumps only)
Possible jammed impeller
- Check to make certain correct fuse rating is installed.
REPLACE ALL DAMAGED WIRING
- Inspect & clean impeller area of any debris
- Make sure that impeller is free to rotate
