Fisher & Paykel Cooktops ER Error: Touch control error

Fisher & Paykel cooktop error code ER is a mid-severity fault meaning Touch control system communication error. An ER fault means the control system cannot be trusted to respond correctly to user input. A 60-second circuit breaker power-cycle clears transient ER faults.

Answer to continue safely

Is it safe to keep using?

No. An ER fault means the control system cannot be trusted to respond correctly to user input. Zones may activate unexpectedly or fail to shut off. Do not use the cooktop until the fault is resolved.

Can I reset the code?

Yes. A 60-second circuit breaker power-cycle clears transient ER faults. If ER returns at power-up or after cleaning the touch panel, the hardware requires professional inspection.

When to stop immediately?

Stop if you notice: ER returns immediately after every power-cycle, Zones activate or change power levels without user input.

Symptoms You May Notice

ER displayed and controls freeze

The display shows ER and the entire touch panel becomes unresponsive; the cooktop cannot be operated.

Random zone activation or power changes

Zones switch on or off without user input, or power levels change spontaneously before ER appears.

Fault appears on startup

ER displays immediately when the cooktop is powered on before any cooking has taken place.

Possible Causes

1

Capacitive touch panel contamination

Grease, cleaning residue, or moisture on the glass surface near the control zone is causing false touch registrations that overwhelm the controller.

DIY Possible
2

Communication fault between touch PCB and main board

The serial communication link between the front touch control PCB and the main inverter board has failed or is experiencing electrical noise.

Requires Professional
3

Damaged touch overlay

Physical damage to the glass surface or the capacitive sensing layer beneath the printed control markings has disrupted the touch sensing array.

Requires Professional
4

Main control board fault

The main PCB has experienced a firmware or hardware fault that prevents it from correctly interpreting signals from the touch panel.

Requires Professional

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Clean the control panel area

    Power off the cooktop and thoroughly clean the touch control zone with a dry microfibre cloth. Remove all grease, cleaning product residue, and moisture.

    Avoid abrasive cleaners on the touch zone — they can damage the capacitive sensing layer beneath the glass surface.

  2. 2

    Power-cycle at the circuit breaker

    Switch off the dedicated circuit breaker for 60 seconds, then restore power. ER caused by transient communication noise often clears after a full power-cycle.

    Note whether ER appears immediately on power-up or only after a period of use — this helps diagnose whether the fault is noise-related or load-related.

  3. 3

    Check for surface damage

    Inspect the glass-ceramic surface in the control zone for cracks, chips, or scratches. Physical damage to the glass can disrupt the capacitive field.

    Do not use a cooktop with a cracked glass-ceramic surface — glass failure risk increases with thermal cycling.

When to Call a Professional

Contact a qualified technician if:

  • Touch PCB to main board communication fault requires circuit testing
  • Touch overlay replacement involves glass-ceramic surface access
  • Main control board replacement is a multi-step technician repair
