J. Troubleshooting Your Swimming Pool Heat Pump: Error Codes
1. The most common problem reported is the heat pump showing a display but not
running its fan and compressor. This is the time delay on start up. From pressing
START/STOP there is a 2 – 3 minute delay before the fan and compressor start.
2. The second most common problem is insufficient flow through the heat pump indicated
by EE 03. If your swimming pool filter has a multiport valve turn off the pool pump and
turn the valve to “recirculate” , restart the pool pump and try the heat pump again. If this
solves the problem make sure your sand filter is backwashed.
3. Another issue is not being able to operate the control panel at all. Look for a small
padlock symbol on the display which means that the controls are locked. To release
this press the up and down arrows together at the same time for about 5 seconds so
that the padlock symbol disappears.
4. During the operating and defrosting process, the heat pump will yield a volume of
condensed water. The condensed water from the cooling coil will drip from the bottom
of the heat pump. Do not assume the condensed water is due to a fault or a leak in the
heat pump.
