Hoover Washing Machine: electrical issue, program restarting, water overfilling

Professional Repair Guide

What is this symptom?

Experiencing issues with your Hoover washing machine? If it's restarting mid-cycle or overfilling with water, you may be facing an electrical fault or pressure switch issue. Common symptoms include error codes like E04 and unexpected resets during wash cycles. Understanding the causes can help you address these problems effectively.

Urgency: Medium

Important Tips for Hoover Models

  • Hoover error code E04 corresponds to water level/pressure faults; check pressure switch and inlet components.
  • Hoover error codes E12–E18 may indicate control board communication faults leading to erratic behavior.

Possible Causes

Faulty or blocked water level/pressure switch causing incorrect water level detection and overfilling

How to Identify: Error code E04 on display; machine continues to fill water past appropriate level; audible water inlet continuing when it should stop

Part: Pressure switch (water level sensor) and pressure hose

Stuck or faulty water inlet valve allowing continuous water entry

How to Identify: Water continues to enter even when machine is off/power disconnected; overfilling or flooding; associated error codes relating to water fill issues (e.g. E02

Part: Water inlet valve (solenoid valve)

Electrical short or component insulation breakdown causing mid-cycle stops or resets

How to Identify: Circuit breaker trips or machine stops mid-cycle; resets when power re-applied; possible burning smell or visible wiring damage

Part: Wiring harness, heater element, motor insulation, mains filter

Control board / PCB fault causing incorrect cycle control and resets

How to Identify: Unexplained restarts or error codes persist after cleaning sensors; resets done but issue returns; error codes indicating communication or PCB fault

Part: Main control PCB
