Why does my Jandy JE3000T Heat Pump not run and display 'FAULT- HIGH REF PRESSURE'?
- L
  Lydia MasonAug 3, 2025
  If your Jandy Heat Pump displays 'FAULT- HIGH REF PRESSURE', ensure the circulating pump is running and there are no water flow restrictions. If you have a two-speed or variable-speed filter pump, try a higher speed. Also, check that all valves are open and properly positioned for adequate water flow to the heat pump. Make sure the filter and skimmers are clean, and verify the water level in the pool. If the heat pump hasn't been used for a while, cycle it on and off up to three times to clear the condition. If the problem persists, it's time to call for service.

What to do if my Jandy JE3000T doesn't run and the control board displays 'FAULT- NO FLOW'?

  If your Jandy Heat Pump displays 'FAULT- NO FLOW', first ensure the circulating pump is on and all necessary valves are in the correct positions. Then, verify the filter and skimmers are clean, and check the water level in the pool. Temporarily turn off any fountains or waterfalls that bypass the heat pump's water inlet. If the issue continues, it's recommended to call for service.

How to troubleshoot a Jandy JE3000T Heat Pump leaking water?
- J
  Julie WoodAug 12, 2025
  If your Jandy Heat Pump is leaking water, turn it off, then turn off the circulating pump for at least one hour to see if the leak stops. If the water leak stops, it's likely just normal condensation. However, if the leak continues after the heat pump has been off for at least an hour, there may be a heat exchanger or plumbing leak, and you should call for service.

What to do if Jandy JE3000T runs but does not heat?
- M
  moorevanessaAug 17, 2025
  If your Jandy Heat Pump is running but not heating, first verify cold air is blowing out the top of the unit. If it's a new installation or the pool water has cooled significantly, run the heat pump continuously for 24-48 hours. If the heat pump has been running for a while, increase the circulating pump time or switch the control board to Maintain Heat function. If heating a spa, ensure no air intake stand pipes are open. If the heat pump still does not heat, call for service.

Why won't my Jandy Heat Pump start, even though the control board display is working?
- R
  robertholtAug 21, 2025
  Your Jandy Heat Pump might be in a 5-minute delay countdown. Ensure the control board thermostat is calling for the heater to turn on by checking the thermostat setting and temperature reading. Also, confirm the heat pump is not accidentally set to cooling mode.

Why won't my Jandy JE3000T start and there is no control board display?
- A
  Andrew WallaceAug 26, 2025
  If your Jandy Heat Pump won't start and the control board display is blank, the breaker or fuse may have tripped. Try resetting the breaker or checking the fuse. If the heat pump still doesn't run after this, call for service. For three-phase models, the phases may be reversed or there may be a loss of phase, in that case, call for service.

What to do if Jandy JE3000T Heat Pump does not run or short cycles and control board display shows: FAULT- LOW REF PRESSURE?
- K
  kimberlyhunterAug 29, 2025
  If your Jandy Heat Pump displays 'FAULT- LOW REF PRESSURE', check that the fan is operating and air is coming out of the top of the heat pump while it's short cycling. If the heat pump isn't running at all, call for service.
