What the E27 Error Means
The E27 error code indicates that the voltage supplied to the dishwasher has dropped below the level required for safe operation. Modern dishwashers are sensitive to power fluctuations and will stop the cycle if the incoming voltage is insufficient to operate components such as the heating element, pumps and control board correctly.
Common Reasons This Error Appears
Low mains voltage
A drop in household mains voltage — which can occur during periods of high demand on the electrical network — can trigger this error.
Faulty extension lead or socket
If the dishwasher is connected via an extension lead or a faulty wall socket, the voltage reaching the appliance may be insufficient.
Overloaded household circuit
Running multiple high-demand appliances on the same circuit simultaneously can cause voltage to drop and trigger this error.
Loose or damaged mains connection
A loose connection at the plug, socket or within the appliance’s power supply can cause intermittent voltage drops.
Safe Checks You Can Try
Check the power supply
Ensure the dishwasher is plugged directly into a dedicated wall socket rather than an extension lead or multi-socket adapter.
Check other appliances on the circuit
If other high-demand appliances such as a washing machine or oven are running on the same circuit, try running the dishwasher alone.
Restart the dishwasher
Turn the appliance off at the mains for a few minutes before restarting. If the voltage drop was temporary, the error should clear.

When To Contact A Professional
If the E27 error appears regularly and is not related to a temporary mains voltage issue, an electrician should check the household wiring and socket. If the fault lies within the appliance itself, a qualified engineer will need to inspect the power supply components.
Internal components should only be inspected or repaired by trained professionals.
