Problem
|
Possible Cause |
Remedy |
| The pump does not run when push button is pressed |
A. No power at electrical outlet
B. You've plugged the controller into an electrical outlet controlled by a wall switch, (such as the outlet under many kitchen sinks that controls the garbage disposal.) |
. Plug the controller into a "hot" (always on) outlet
|
|
C. Power cord is not secured to pump and valve
D. Wire to push button is not connected well |
. Shut off power, then make sure wires have good contact |
| E. The temperature setting is already sensing "hot" water so the pump is not being activated |
. Reset the water temperature setting on the controller to be less sensitive |
The water is not hot enough
|
A. Pump or valve was installed with water flow going in the wrong direction
B. There is something in the piping that has blocked the flow of water |
. Check the arrows on the housings of the valve and pump to make sure they point in the correct direction
. Check the piping for obstruction |
| There is hot water at the cold water tap |
A. The water temperature sensor is positioned incorrectly
B. The temperature sensitivity setting now in place is too low, so the pump is not shutting down soon enoug
|
. Check the position of the water temperature sensor to make sure it is firmly attached to the pipe
. Carefully turn the pot hole adjustment 1/8 turn at a time clockwise (use a small standard screwdriver)
|
| Water is not hot enough when pump shuts down |
A. The temperature sensitivity setting now in place is too low, and the pump is turning itself off too soon |
. Carefully turn the pot hole adjustment 1/8 turn at a time counter clockwise (use small standard screwdriver) |
| There is hot water in the cold water lines only |
The pump is installed backwards |
Reinstall the pump correctly |
