What Does Error Code E4 Mean on a Fisher & Paykel Washing Machine?

Water inlet fault — insufficient fill.

E4 fires when the control board detects that the wash bowl has not reached the expected water level within the allotted fill time. The board monitors the pressure/level sensor against a timer; if inflow is too slow or absent, it flags an inlet fault. This differs from E5, which relates to drain or overflow conditions — E4 specifically signals inadequate fill, whether from a closed valve, clogged inlet screen, weak supply pressure, or a failed inlet solenoid.

Models affected: Fisher & Paykel top-load washers with electronic fill control, including models such as the WH2424P1

What owners report: Owners commonly report E4 appearing at the start of a cycle, often after plumbing work or a partially reopened supply valve. A frequent quick win is simply confirming both taps are fully open and rinsing the mesh inlet screens, which can be gradually blocked by sediment or scale.

Frequently Asked Questions

Can I keep using my Fisher & Paykel Washing Machine when error E4 appears? +

You often can for a cycle or two, but the water-supply issue behind E4 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.

What most commonly causes E4 on a Fisher & Paykel Washing Machine? +

Across reported Fisher & Paykel washing machine repairs, the most frequent is supply valve closed (40% of cases), inlet screen blocked (30%), then low water pressure (20%). Check them in that order before replacing any parts.

E4 keeps coming back after a reset — what should I check next? +

A reset only clears the stored E4 fault; if it returns, the water-supply problem is still present. Move on to the physical checks — check supply valves, then clean inlet screen — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.

A DIY repair typically runs $0–$90 in parts, versus $150–$300 for a professional service call, so handling it yourself saves around $150. Expect the work to take about 10–20 minutes.
