What to do if my Zodiac PM40 Heat Pump shows E3 error?
- EEric FrederickAug 17, 2025
If your Zodiac Heat Pump displays the error 'E3 Faulty water flowmeter', it could be due to several reasons. First, check if the flowmeter is incorrectly positioned and re-make the connections. If the connections are correct, ensure there is sufficient water flow; if not, increase the water flow rate. The flowmeter itself might be broken, requiring a replacement. Lastly, a faulty filter pump can also trigger this error, so consider repairing or replacing it.
