E27
Balay E27 on a dishwasher: insufficient mains voltage
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
The dishwasher detects that the mains voltage is insufficient. Balay makes clear this is not an appliance fault and that you need an electrician to check the electrical supply.
Safety first
Stop and check this first
- Do not open the consumer unit or the socket to check the voltage: it is work for an electrician, as Balay says for this code.
Safe checks you can perform
- That the code is E27
- When E27 appears
- Electrical check by an electrician
Leave these tasks to a qualified professional
- Do not attempt this professional task: Measure voltage at the socket and circuit
- Do not attempt this professional task: Appliance check if the supply is correct
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Measure voltage at the socket and circuit
What they doThe electrician measures the voltage at the dishwasher's socket with a multimeter and checks the circuit that feeds it.
They must show youthe voltage measured at the socket.
In writingthe measured value and what was corrected in the installation.
Appliance check if the supply is correct
What they doIf the electrician confirms correct voltage and E27 remains, Balay's official service checks the dishwasher's power supply.
They must show youthe electrician's report and a test run after the repair.
In writingthe part replaced and the reason.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
That the code is E27
- Who:
- you.
- How:
- read the code on the display and compare it with Balay's code page.
- Result that matters:
- confirming that it is E27, insufficient mains voltage.
- If it is E27:
- it is not an appliance fault; continue with the checks.
- If it is another code:
- see its page; the advice changes.
- Evidence to keep:
- photo of the code with date and time.

When E27 appears
- Who:
- you.
- How:
- note the time and which other appliances were running when E27 appeared, without touching the consumer unit or the socket.
- Result that matters:
- a pattern that helps the electrician.
- If it matches other appliances running or certain times of day:
- tell the electrician; it guides the measurement.
- If it appears every time:
- that is useful too; the voltage drop may be constant.
- Evidence to keep:
- list with date, time and appliances running.

Electrical check by an electrician
- Who:
- an electrician.
- How:
- measures the voltage at the dishwasher's socket and checks the circuit and installation that feed it, as Balay asks for E27.
- Result that matters:
- whether the voltage reaching the appliance is sufficient.
- If low voltage is confirmed:
- the repair is in the installation, not the dishwasher.
- If the supply is fine and E27 remains:
- the supply no longer explains the code; call Balay's official service with the electrician's report.
- Evidence to keep:
- electrician's report with the measured voltage.
Measuring mains voltage and opening the consumer unit or socket is work for an electrician only. Do not do it yourself.

What it means
According to Balay, E27 means the mains voltage is insufficient. The dishwasher's control monitors the voltage it receives through the plug; the problem can be in the home's installation, in the circuit or in the socket that feeds the appliance. Balay says it is not a fault and refers you to an electrician. The code does not say where in the installation the voltage drops, only that it arrives too low.
