What causes a high-pressure fault in Zodiac Z200 MD5 Heat Pump, and how to resolve it?
- B
  Brandon RobinsonAug 17, 2025
  A high-pressure fault in your Zodiac Heat Pump can be caused by air and water emulsion entering the device; in this case, check the pool's hydraulic circuit. Increase flow using the bypass and ensure the pool filter isn't clogged. Wait for the temperature to fall. Check the flow controller, clean the water condenser, and close the bypass valve to increase the flow rate through the device.

Why does my Zodiac Z200 MD5 trip the circuit breaker?
- P
  Patrick BradyAug 30, 2025
  The Zodiac Heat Pump might be tripping the circuit breaker because the breaker isn't correctly sized or the cable section used is not the right one. Also, the supply voltage could be too low; in this case, contact your electricity supplier.

What to do if my Zodiac Z200 MD5 Heat Pump is not working?
- D
  Darin AlvarezSep 2, 2025
  If your Zodiac Heat Pump isn't working, check the supply voltage and the F1 fuse. Also, the heat pump stops heating when the setpoint temperature is reached: the water temperature is higher than or equal to the setpoint temperature. If the water flow rate is zero or not enough, the heat pump stops: ensure water is circulating correctly. The heat pump also stops when the outdoor temperature falls below 5 °C for standard models or -5 °C for “Defrost” models. Finally, it may have detected an operating fault.

What to do if my Zodiac Z200 MD5 is working but the water temperature does not increase?
- C
  Charles BeckerSep 5, 2025
  If your Zodiac Heat Pump is running but the water temperature isn't increasing, it may have detected an operating fault. Check that the automatic filling valve is not stuck in the open position, as this will keep supplying cold water. If the air is cool, install a heat-insulated cover on your pool to reduce heat loss. Also, if the evaporator is clogged with dirt, clean it to restore performance. Ensure the external environment isn't hindering the heat pump and that the heat pump is the right size for your pool and environment.

Why is my Zodiac Z200 MD5 draining water?
- S
  Shannon McdonaldSep 8, 2025
  The water draining from your Zodiac Heat Pump is often condensation, which is moisture in the air condensing on cold components, especially the evaporator. To check if it's a pool circuit leak, shut down the heat pump, wait a few minutes, and run the filtration pump to circulate water. If water continues to flow through the condensation drain, there is a water leak, and you should contact your reseller.

Why does my Zodiac Z200 MD5 not start heating straight away?
- B
  bsullivanSep 12, 2025
  Your Zodiac Heat Pump might not start heating immediately because it remains paused for 5 minutes on start-up. Also, when the setpoint temperature is reached, the heat pump stops heating if the water temperature is higher than or equal to the setpoint temperature. If the water flow rate is zero or insufficient, the heat pump will stop; check that water is circulating correctly and that hydraulic connections are correct. The heat pump also stops if the outdoor temperature falls below 5 °C for standard models or -5 °C for “Defrost” models. Finally, it may have detected an operating fault.

What does 'Deicing cycle fault (>20 minutes)' mean on my Zodiac Heat Pump and how can I fix it?
- V
  Vincent MorseSep 12, 2025
  A deicing cycle fault lasting more than 20 minutes on your Zodiac Heat Pump could be due to a low air temperature; wait until the temperature is within the operating range. Alternatively, clean the evaporator.
