Troubleshooting
Symptom
Motor will not run.
Motor runs hot and overload
kicks off.
Motor runs but no water is
delivered*.
* Stop pump; then check
prime before looking for
other causes. Unscrew
priming plug and see if
water is in priming hole.
Pump does not deliver water to
full capacity.
For parts or assistance, call Simer Customer Service at 1-800-468-7867
Possible Cause(s)
Disconnect switch is off.
Fuse is blown or circuit breaker tripped.
Starting switch is defective.
Wires at motor are loose, disconnected, or
wired incorrectly.
Motor is wired incorrectly.
Voltage is too low.
Pump cycles too frequently.
Pump in new installation did not pick up
prime through:
1. Improper priming.
2. Air leaks.
3. Leaking foot valve or check valve.
Pump has lost prime through:
1. Air leaks.
2. Water level below suction pipe inlet.
Foot valve or strainer is plugged.
Impeller is plugged.
Check valve or foot valve is stuck shut.
Pipes are frozen.
Foot valve and/or strainer are buried in
sand or mud.
Water level is too low for pump setup to
deliver water.
Water level in well is lower than estimated.
Steel piping (if used) is corroded or limed,
causing excess friction.
Piping is too small in size.
Air leak in suction line.
Need more driven points.
Corrective Action
Be sure switch is on.
Replace fuse or reset circuit breaker.
DISCONNECT POWER; Replace starting switch.
Refer to instructions on wiring. DISCONNECT POWER; check and tighten
all wiring.
Capacitor voltage may be hazardous. To discharge capacitor,
hold insulated handle screwdriver BY THE HANDLE and short capacitor
terminals together. Do not touch metal screwdriver blade or capacitor terminals.
If in doubt, consult a qualified electrician.
Refer to instructions on wiring.
Check with power company. Install heavier wiring if wire size is too small (See
Electrical / Wiring Chart).
See section below on too frequent cycling.
In new installation:
1. Re-prime according to instructions.
2. Check all connections on suction line.
3. Replace foot valve or check valve.
In installation already in use:
1. Check all connections on suction line and shaft seal.
2. Lower suction line into water and re-prime. If receding water level in well
exceeds 20' (6m), a deep well jet pump is needed.
Clean foot valve or strainer.
Clean impeller.
Replace check valve or foot valve.
Thaw pipes. Bury pipes below frost line. Heat pit or pump house.
Raise foot valve and/or strainer above bottom of water source. Clean foot valve
and strainer.
A deep well jet may be needed if your well is more than 20' (6m) depth
to water.
A deep well jet may be needed if your well is more than 20' (6m) depth
to water.
Replace with plastic pipe where possible, otherwise with new steel pipe.
Use larger piping.
Check all connections, inspect line for cracks (test with soapy water while pump
is running - a leak will pull soap suds into hole).
Add driven points to suction line until performance is O.K.
