Trouble Shooting

Symptom

Possible Cause(s)

Corrective Action

Pump won’t start

Power supply is not connected

Check the fuse/circuit breaker or 

the power connection

Capacitor is damaged

Change capacitor

Motor blockage

Check that rotor shaft rotates 

freely.

There is noise in the 

system

The pump flow is too high

Reselect pump

Air in the system

Vent the system

The pump head is too high

Reselect pump

Noise in the pump

Air in the pump

Vent the pump

Cavitation due to insufficient 

inlet pressure

Increase system pressure within 

permissible range

Wet Rotor Circulator Pumps   

PFWRC67S1U

OPTIONAL:  PFDT - 7-Day Digital Timer

The digital, programmable timer allows for control of the 

circulator (on / off) at designated times (up to four custom 

settings per 24 hour period) for up to 7 days (similar to a 

programmable thermostat). The timer is plugged into a standard 

wall outlet and the circulator pump is then plugged into the 

timer allowing for time control of the pump. This unit has an 

internal battery backup which will, in the event of loss of AC 

power, power the unit and save / maintain program settings 

(battery will last for 48 hours before needing to be recharged). 

NOTE: The Digital timer (PFDT) and Aquastat (PFSOA) 

can ALSO be used together, in tandem to allow for BOTH 

temperature AND time control.

OPTIONAL:  PFSOA - Snap on Aquastat

The Aquastat simply “clips” onto any material 1/2” ID or 3/4” ID 

piping. It then plugs into a standard wall outlet. You would then 

plug in the power cord for the circulator into the aquastat plug 

and it will turn the circulator on and off automatically at fixed 

set points (ON 98°F and OFF at 114°F) allowing for temperature 

control of pump.

 

NOTE: The Digital Timer (PFDT) and Aquastat (PFSOA) 

can ALSO be used together, in tandem to allow for BOTH 

temperature AND time control.
