What is actually happening
An RCD trips when current leaks to earth. When a machine trips it the moment it is switched on, the leak is usually in the mains filter or the wiring. When it only trips once the wash warms up, it is nearly always the heating element, which has cracked and is leaking to earth as soon as it energises — the timing is the diagnosis.
The Blomberg fault codes that point at this
A Blomberg washing machine will usually tell you what it thinks is wrong before anyone opens it up. These are the codes we hold for this make that relate to tripping the electrics:
- E01 — The machine can't read the water temperature — the sensor that tells it how hot the water is has gone faulty or lost its connection.
- E02 — The machine can't get a signal through its heating element, so it has stopped trying to heat the water.
- E03 — The control board has spotted that the heating element is staying switched on when it shouldn't be, so the machine stops heating altogether to protect you and the load.
- E04 — The control board has lost control of the water inlet valve — the machine can keep filling with water even when it shouldn't be, so it stops the programme.
- E06 — The circuit on the main control board that switches power to the drum motor has failed, so the machine has stopped rather than risk the drum running out of control.
- E10 — The circuit on the main control board that switches your door lock has failed short, so the machine can no longer control the lock properly and stops the wash.
- E15 — The machine has lost a sensible reading from its flowmeter — the small sensor that counts how much water is going in — so it stops rather than fill blind.
- E20 — The machine has spotted a fault in the electronics that switch the door lock on and off — the switching device is stuck closed, so the machine won't run a wash.
If yours is showing one of those, that is a much shorter conversation than a general fault — tell us the code when you book and the engineer can often carry the part.
The usual causes on a Blomberg washing machine
- A failed heating element leaking to earth — the classic "trips ten minutes in" fault
- A failed mains interference filter — trips the instant it is switched on
- Water ingress onto wiring from a leak elsewhere in the machine
- A failed motor or damaged cable
What you can safely check yourself
- Note exactly when it trips — at switch-on, at fill, or once the water heats. That timing tells an engineer most of what they need
- Try a cold wash: if a 30°C cycle completes and a 60°C one trips, it is the element
- Leave the machine unplugged if it trips the house repeatedly — this one is not worth living with
Still tripping the electrics?
Most of these need an engineer once the checks above are done. £66 including VAT for an engineer to come out and diagnose it, or £84 in total including VAT if it is put right on the visit and no parts are needed. Any parts needed are quoted on site before we fit them — you decide. Every repair carries a 90-day workmanship guarantee.
Our engineers work on Blomberg machines week in, week out, so they arrive knowing the machine rather than reading the back of it. Local engineers across Nottinghamshire, Derbyshire and Leicestershire.

Common questions
Why is my Blomberg washing machine tripping the electrics?
Switching the machine on, or reaching a certain point in the cycle, takes out the power to the house. An RCD trips when current leaks to earth. When a machine trips it the moment it is switched on, the leak is usually in the mains filter or the wiring. When it only trips once the wash warms up, it is nearly always the heating element, which has cracked and is leaking to earth as soon as it energises — the timing is the diagnosis.
Can I fix a Blomberg washing machine tripping the electrics myself?
Note exactly when it trips — at switch-on, at fill, or once the water heats. That timing tells an engineer most of what they need. Try a cold wash: if a 30°C cycle completes and a 60°C one trips, it is the element. Leave the machine unplugged if it trips the house repeatedly — this one is not worth living with. Beyond those checks this one normally needs an engineer.
What Blomberg error codes mean tripping the electrics?
Blomberg washing machines report this through their own fault codes. The ones that point at tripping the electrics are E01, E02, E03, E04, E06, E10. If your machine is showing one of those, that narrows it down considerably — each has its own guide on this site.
How much does a Blomberg washing machine repair cost?
£66 including VAT for an engineer to come out and diagnose it, or £84 in total including VAT if it is put right on the visit and no parts are needed. Any parts needed are quoted on site before we fit them — you decide. Every repair carries a 90-day workmanship guarantee.
