Grundig E05 on a washer dryer
Heating fault — the machine is not heating the wash water.
The same code appears on Beko and Blomberg machines — they share the same control platform.
Needs an engineer
Mains electrical, gas or sealed-system work
About 50 min to work through
£95–£220
What E05 actually means
The board asked for heat and the temperature did not rise as expected, so it stopped rather than continue blind. Either the element has gone open circuit, or the sensor reporting temperature has failed. Both sit behind the drum next to mains wiring, which makes this an engineer job.
Before you start
Electrical safety: The heating circuit carries high current at mains voltage. Do not test or replace the element yourself unless you are qualified to work on mains appliances.
What causes it, most likely first
Failed heating element
Most likelyThe element goes open circuit, usually after limescale has insulated it and driven it to overheat.
Heating element£15–£40 for the partEngineerFailed NTC temperature sensor
CommonThe sensor stops reporting a rising temperature, so the board concludes heating has failed when it has not.
NTC temperature sensor£8–£22 for the partEngineerCorroded element terminals
OccasionalDamp behind the drum corrodes the spade connections until the circuit reads as broken.
Wiring loom / connector£10–£45 for the partEngineerHeater relay failure on the control board
OccasionalThe relay switching the element fails open or welds shut. Needs live testing to distinguish from a dead element.

How to fix it, step by step
Confirm the symptom
Run a 60°C wash and feel the door glass twenty minutes in. Cold glass throughout points at the element or relay; warm glass suggests the sensor.
30 minPower-cycle
Switch off at the wall for five minutes and restore power to rule out a latched fault.
10 minUse cold cycles in the meantime
A cold or 20°C programme avoids the heating circuit on most models. Stop using the machine entirely if you smell burning.
5 minBook an engineer with the code
Quoting E05 tells them to bring an element and to test the NTC and relay, which often saves a second visit.

Parts you might need
Typical UK prices for the part alone, before fitting. Worth knowing before you accept a quote — the part is often a small share of what a repair is priced at.
NTC temperature sensor
A small thermistor that tells the control board how hot the water is. When it fails the board usually assumes the worst and stops heating.
£8–£22Wiring loom / connector
Chafed wires and corroded connectors mimic dead components. An engineer will always check continuity before condemning a part.
£10–£45Heating element
The element sitting under the drum that heats the wash water to the selected temperature.
£15–£40Main control board (PCB)
The appliance brain. Genuine boards are expensive and often need configuring to the model, so this is rarely a DIY part.
£70–£220
Worth repairing, or replace it?
At the top of this range the repair costs a significant share of a graded replacement, which typically starts around £280. Worth getting the quote first, then deciding — on a machine under about five years old a repair usually still wins.
