Error code ER42
Appliance Cooktop
Affected model series Induction cooktop — confirm the rating-plate model before acting
Quick answer

ER42 on a Fisher & Paykel Cooktop — plain-language overview; confirm against your model docs.

Model compatibility: Fisher & Paykel reuses codes across series and model years, so ER42 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

This page provides general guidance while ER42 is matched to Fisher & Paykel docs for the Induction cooktop — fault codes platform. Confirm the label on your rating plate before relying on any interpretation.

Signs

Symptoms you may notice

  • The induction cooktop display shows ER42 during or after use.
  • One or more cooking zones may stop heating, cycle on/off unexpectedly, or refuse to start while ER42 is shown.
  • An audible alert or flashing zone indicator may accompany the ER42 display.
Before you call

Safe checks you can make

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.

  • Let the cooktop cool fully, then wipe the glass surface clean and dry — spills, moisture, or metal objects near the controls can sometimes affect touch controls.
  • Confirm only induction-compatible cookware of a suitable size is centered on the zone.
  • Switch the cooktop off at the wall or breaker, wait a few minutes, then restore power and retry once.
  • Check that nothing is obstructing the ventilation gap under or around the cooktop.
  • Record the full model and serial number from the rating plate.

Important safety warning. Do not open the cooktop body, access wiring or the control/power electronics beneath the glass, or attempt to repair a cracked ceramic/glass surface yourself. If you notice smoke, sparks, arcing, or a burning smell, switch off power at the wall or breaker if safe to do so and call a professional immediately.
