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 enough |
• 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 |
