What this error means
Control board communication fault — internal electronics are not communicating correctly
The E67 error indicates a communication failure between the main control board (PCB) and another internal electronic module - Typically the motor control board, the display module, or a sensor subsystem. It can be caused by a wiring connector that has worked loose, moisture or corrosion on a connector, damage from a power surge, or a failed control board. This fault always warrants careful investigation before assuming the board needs replacing.

Step-by-step
Symptoms to look for
- Machine will not start or stops immediately after starting
- E67 error displayed as soon as a programme is selected
- Controls appear unresponsive or only partially respond
- Machine starts but stops unexpectedly mid-cycle with no other fault code
Diagnostic steps
Unplug the machine and press and hold the power button for 15 seconds to drain residual power from the control board capacitors. Leave unplugged for a minimum of 10 minutes. Plug back in and retry.
With the machine unplugged, remove the top panel by undoing the two screws at the rear and sliding the panel backwards. The main control board is typically in a rectangular plastic housing beneath the top panel, usually towards the rear left. Take photographs of all wiring connections before touching anything — these will help you reassemble correctly.
Working systematically from one side to the other, locate every multi-pin wiring connector attached to the control board. Each one should be pressed together firmly and evenly with no pins bent and no wires pulling out. Pull each connector apart gently and press it back in firmly until it clicks into place. Check in particular the connectors that link the main board to the display module and to the motor control board as these are the most common communication paths to fail.
Examine each connector and the board terminals for any green or white deposits indicating corrosion, or any sign of moisture ingress — water droplets, watermarks, or rust-coloured staining. If corrosion is visible on connector pins, clean them gently with a dry cotton bud.
With the board accessible, examine its surface closely for any burnt components — they will appear discoloured, bulging, or have a brown scorch mark on the board surface around them. Look for cracked solder joints on large connectors. Check that no loose debris, moisture, or rodent damage is visible.
Reconnect all wiring firmly, replace the top panel and plug the machine back in. Select a standard 40-degree programme. If the machine completes the programme without displaying E67, the fault has been resolved by reseating the connectors. Run 2 to 3 further cycles to confirm stability before returning the machine to normal use.
When to call an engineer
- Visible burnt components or scorch marks on the control board surface
- Corrosion on control board connector pins that cannot be cleaned with a dry cotton bud
- E67 persists immediately after every power cycle despite firm connector reseating
- Control board has been exposed to water ingress — replacement required
