Hoover E22

Hoover error code E22 indicates: Hoover H-WASH 300 / 500 / 700 Eco-Power Inverter Washer: Siphoning drain detection E22; water level drops continuously during active wash fill cycle without pump activation..

The primary root cause for Hoover code E22 is: On Hoover washing machines featuring Eco-Power permanent magnet brushless motor, Power Care System premix injection, and hOn AI intelligence: Drain hose installed too low (<65 cm height), drain hose pushed too far into standpipe creating airtight siphon seal..

To resolve error code E22: Ensure top of drain hose bend is suspended between 65 cm and 100 cm above floor level. Use anti-siphon curved elbow and provide air gap in standpipe. Rotate dial to Off, hold down Start/Pause and Spin Speed keys for 6 seconds until 'rES' appears on the digital readout, then power cycle.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Hoover code E22 persists, the physical component causing On Hoover washing machines featuring Eco-Power permanent magnet brushless motor, Power Care System premix injection, and hOn AI intelligence: Drain hose installed too low (<65 cm height), drain hose pushed too far into standpipe creating airtight siphon seal. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Mechanical Pressure Switch Contacts / Inductive Frequency Sensor across Across switch spade contacts with harness unplugged; electronic output: 40Hz–50Hz frequency signal. Expected nominal reading is Mechanical: Continuity 0.0Ω–0.2Ω (Empty: 11-12, Full: 11-14). Electronic: 20Ω–45Ω coil resistance.. Tolerance: Mechanical switch contacts must transition cleanly on gentle breath pressure. Coil ~22Ω ±5%..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
