  Nicholas Harris IIIJul 30, 2025
  If your Zodiac Heat Pump displays a 'FAULT- NO FLOW' error, it means that the circulating pump might not be on, or the valves are not in the correct positions. First, verify that the circulating pump is indeed running and that all necessary valves are correctly positioned. Also, ensure that the filter and skimmers are clean, and the water level in the pool is adequate. Temporarily disable any fountains or waterfalls that might be bypassing the heat pump's water inlet. If the problem persists, further assistance is needed.

What to do if my Zodiac Jandy EE-Ti Heat Pump shows 'FAULT- HIGH REF PRESSURE'?

  Leslie ChangAug 2, 2025
  If your Zodiac Heat Pump displays 'FAULT- HIGH REF PRESSURE', it could be due to the circulating pump not running or restrictions in the water flow to the heat pump. Ensure the circulating pump is active and that there are no obstructions hindering water flow to the heat pump. Verify that all necessary valves are correctly positioned to allow proper water flow. If the heat pump hasn't been used for a while, try cycling it on and off up to three times to resolve the issue. If the problem persists, it is recommended to call for service.

  If your Zodiac Heat Pump isn't running or is short cycling and the control board displays 'FAULT- LOW REF PRESSURE,' it could mean the fan isn't working, or air isn't coming out of the top of the heat pump. Check that the fan is running and air is being expelled from the top of the unit while it is short cycling. If the heat pump does not run at all, it is recommended to call for service.

How to fix a Zodiac Jandy EE-Ti that won't start and has no display?
- S
  Sarah DavisAug 11, 2025
  If your Zodiac Heat Pump isn't starting and the control board display is blank, a possible cause is a tripped breaker or a blown fuse. Try resetting the breaker or checking the fuse. If the heat pump still fails to start after this, it is recommended to call for service. For three-phase models, this issue could also be due to reversed phases or a loss of phase, in which case you should call for service.

Why is my Zodiac Jandy EE-Ti Heat Pump leaking water?
- K
  Kayla StevensAug 15, 2025
  If your Zodiac Heat Pump is leaking water, it could indicate a heat exchanger or plumbing leak. To investigate, first turn off the heat pump and then turn off the circulating pump for at least one hour to see if the water leak stops. If the water leak continues even after the heat pump has been shut off for at least one hour, it is recommended to call for service.

Why won't my Zodiac Heat Pump start if the display is on?

  Karla Mendoza MDAug 20, 2025
  If your Zodiac Heat Pump isn't starting but the control board display is working, it might be in a 5-minute delay countdown. Ensure the control board thermostat is set to call for heat, verifying both the thermostat setting and the temperature reading. Also, confirm that the heat pump isn't accidentally set to cooling mode.

Why is my Zodiac Jandy EE-Ti Heat Pump running but not heating the water?
- M
  Michael MedinaAug 25, 2025
  If your Zodiac Heat Pump is running but not heating, several factors could be at play. If the heat pump has just been installed or the pool water has cooled down significantly, allow the heat pump to run continuously for 24-48 hours to properly heat the water. If the heat pump has been running for a while, try increasing the circulating pump time or switch the control board to Maintain Heat function. If you are heating a spa, make sure that no air intake stand pipes are open. If the heat pump still does not heat, it is recommended to call for service.
