Why is my Zodiac Heat Pump working but not heating the water?
- C
  Carolyn MarksAug 2, 2025
  If your Zodiac Heat Pump is working but the water temperature isn't increasing, there could be several reasons. The automatic water filling controller might be stuck in the open position; check that it is not stuck. Excessive heat loss could also be the issue; consider installing a heat-insulated cover on your pool. A dirty evaporator can hinder the heat pump's ability to capture enough calories; clean it to restore its efficiency.

  Eduardo HullAug 7, 2025
  If your Zodiac Heat Pump is not working, start by checking the power voltage and fuses if there is no display. Additionally, ensure the water is circulating correctly in the heat pump, as it will stop if the water flow rate is insufficient or zero. The heat pump also stops heating when the setpoint temperature is reached or if it detects an operating fault. The heat pump will also not work if the outdoor temperature is outside of its operating range.

Why does my Zodiac PX 50 Heat Pump keep tripping the circuit breaker?
- C
  Charles GlennAug 11, 2025
  If your Zodiac Heat Pump trips the circuit breaker, it could be due to a few reasons. The circuit breaker may not be correctly sized, or the cable section used might not be appropriate. In this case you need to check that the circuit breaker is correctly dimensioned and that the cable section used is appropriate. Also, the supply voltage might be too low, in this case you should contact your electricity supplier.

Why is my Zodiac PX 50 Heat Pump discharging water?
- H
  Heather Frederick DVMAug 15, 2025
  The Zodiac Heat Pump may discharge water due to condensation, where moisture in the air condenses on cold components, especially the evaporator. You should check that the water is not coming from a leak in the pool circuit on the heat pump. If there is a water leak in the heat pump, contact your retailer.

Why is my Zodiac Heat Pump 'smoking'?
- C
  charles85Aug 20, 2025
  The Zodiac Heat Pump may appear to be 'smoking' because it has come to the end of the defrost cycle; water has changed to a gaseous state and passes through the grid. However, if your heat pump is not in its defrost cycle, this is not normal, you should switch off and disconnect the heat pump immediately and contact your retailer.

Why does the fan run but the compressor stop on my Zodiac Heat Pump?
- S
  Shelby BautistaAug 23, 2025
  The fan in your Zodiac Heat Pump may run while the compressor stops intermittently without an error message because, under normal operation, the heat pump performs defrost cycles if the outdoor temperature is low. Also, the heat pump might not be capturing enough calories due to a dirty evaporator; clean it to restore its performances.

How to solve Zodiac PX 50 not starting to heat immediately?
- A
  amandabeanAug 28, 2025
  Your Zodiac Heat Pump may not start heating immediately if the setpoint temperature has already been reached, meaning the water temperature is at or above the setpoint. In this case, check that the water is circulating correctly in the heat pump and that the hydraulic connections are correct. It could also be that the outdoor temperature is outside the heat pump's operating range, or that the heat pump has detected an operating fault.
