E2: insufficient supply voltage

What does E2 mean?

The pump is detecting that the electrical voltage being supplied to it is too low. This can prevent the pump from starting or operating correctly.

• Loose electrical connections to the pump.
• Issues with the electrical circuit supplying power.
• Voltage fluctuations or sags in your electrical system.
• Overloaded electrical circuit.

1. 1

   Check that the pump's power cable is securely plugged into its outlet or terminal block.

2. 2

   Verify that the circuit breaker for the pump's circuit has not tripped; reset it if necessary.

3. 3

   Ensure no other high-power appliances are causing a voltage drop on the same circuit.

4. 4

   If the problem persists, an electrician should check the incoming voltage at the pump's connection.
