Induction hob shows E8 and one side (left or right group of zones) is inoperative.

Safety first: Disconnect from mains and wait for capacitors to discharge before handling the power modules.

Technician steps:

• Remove the hob and identify the separate left and right induction power modules (common on multi‑zone Caple hobs).
• Check for onboard fuses on the affected module and test them for continuity.
• Inspect for burn marks, cracked solder joints, or bulging capacitors.
• Verify that the supply harness from the mains terminal block to the module is intact and correctly connected.
• Swap the signal/control connectors between modules (if identical) to confirm whether the fault follows the module or the control signal.

Remedy: Replace the defective induction power module. Ensure good thermal contact with the chassis and refit any insulating pads as originally installed.
