Washing Machine
E112
The E112 error code on a Grundig washing machine indicates a water heating fault — the machine cannot reach or maintain the correct wash temperature. It’s a moderately serious fault that will stop most wash cycles from completing correctly, but it’s often fixable without a call-out.
What does this error mean?
E112 tells you that the washing machine’s control board has detected a problem with the water heating system — either the water isn’t heating at all, isn’t heating fast enough, or the machine is receiving an incorrect temperature reading. Grundig machines share platform architecture with Beko and Blomberg, so E112 consistently points to the heating circuit: the heater element, the NTC temperature sensor, or the wiring connecting them to the PCB. Left unresolved, your laundry will come out cold and under-washed.

🔍 Likely causes
🛠️ Step-by-step fix
Power off and reset: Switch the machine off at the plug, wait 10 minutes, then restart and run a short cotton cycle. A transient sensor glitch can trigger E112 and a cold restart clears it.
Check your water supply is hot enough: E112 can appear if incoming cold-fill water is unusually cold and the element is struggling. Confirm the cold-water supply valve behind the machine is fully open.
Run a descaling cycle: If you’re in a hard-water area, use a proprietary washing machine descaler (e.g. Calgon or Durgol) on a hot empty cycle. Limescale on the element is a leading cause of E112 on older machines.
Inspect the element and NTC sensor (DIY-capable with care): Unplug the machine. Pull the machine forward and remove the back panel (usually 4–6 screws). Locate the heating element at the bottom of the drum — check for visible burn marks or heavy scale. The NTC thermistor clips onto or sits beside the element; check its connector is firmly seated. Do NOT proceed if you are unsure about working inside appliances — call a professional instead.
Test the NTC thermistor with a multimeter: A healthy NTC typically reads around 10,000 ohms (10kΩ) at room temperature. A reading of zero or infinity means the sensor has failed and needs replacing — it’s a cheap part (£5–£15) and straightforward to swap.
If the element is faulty, replace it: Genuine or compatible Grundig heating elements cost £20–£45. Drain the machine fully first, disconnect the wiring terminals and mounting nut (usually 10mm), swap the element, and refit. If you are not confident handling internal electrical components after unplugging, stop here and call an engineer.
📞 When to call a professional
Call a qualified appliance engineer if the reset and descale steps don’t clear the code, or if you find burn marks, melted wiring, or a visibly damaged element inside the machine. Tell the engineer: ‘My Grundig washing machine is showing error code E112 — I believe it’s a heating circuit fault, possibly the element or NTC sensor.’ This saves diagnostic time and may reduce your call-out cost.
⚖️ Repair or replace?
A professional repair for E112 — typically an element or NTC sensor replacement — will cost £80–£140 including labour in the UK. If your machine is under 5 years old, repair is almost always worthwhile. For machines 8 years or older, weigh the repair cost against a new mid-range 8kg Grundig or equivalent (£300–£450); if the PCB is also suspect, replacement often makes more financial sense.
