Check wiring against the pump installation manual diagram, check all connections for tightness, shorts, burns, damage.

A loose wire can cause intermittent pump or other electrical device failiures as well as a hard failure that means no power or blown fuses.

Rewire or repair or replace wiring

WATER PUMP WIRING DAMAGE

Burned out pump motor

Check that the pump pressure control switch is trying to turn on the pump and that there is voltage at the pump wiring

Repair or replace the pump motor

ELECTRIC MOTOR DIAGNOSTIC GUIDE

Bad motor control switch

Check the control switch contacts for burning or wear.

If the motor control is a well pump pressure control switch,check the pressure control switch settings - cut-in and cut-out; inspect for burned, pitted switch contacts or for dirt or wear.

For water pumps, adjust or replace the pressure control switch.

Temporary emergency repair by cleaning the switch contacts may be possible.

See WATER PUMP PRESSURE CONTROL SWITCH 

Bad pump pressure control switch

Check the tubing connecting the pressure switch to the pump housing for clogging

Clean or replace the tubing and be sure the connections are not leaky - an air leak will prevent the switch from sensing pressure properly

Bad water pump control switch tubing

Clogged or leaky tubing connecting a water pump pressure control switch to the water system results in failure to properly sense and respond to water pressure.

Debris clogging can also occur in the bottom of the pressure control switch where it mounts or connects to the tubing.

Check and clear tubing blockage (blow air through tubing). Or install new tubing.

Be sure tubing is proper diameter and type to seal properly with other fittings.

Tighten tubing fittings to be sure there are no water or air leaks. Soap solution may help find air leaks in tubing fittings.

Clear or replace clogged pressure control switch if the bottom sensor opening is clogged and cannot be cleared.

PUMP PRESSURE CONTROL REPLACE 

Bad pump impeller or impeller seal leak

Turn off electric power to pump, see if you can move the impeller or motor - if it won't turn it is jammed or damaged

Remove obstruction in impeller housing, inspect for and replace damaged impeller or frozen motor.

Bad pump motor starting capacitor

Use a VOM in ohms setting to check resistance across the capacitor. If the meter does not move (no current flows) the capacitor is "open". If there is zero resistance the capacitor is shorted.

Replace the starting capacitor

Pump motor shorted out, jammed, burned up

Fuse blows or breaker trips as soon as the pump tries to turn on. If the external wiring is ok (no short circuits) the motor is shorted internally

Replace the pump motor
