Washing Machine
E93
The E93 error code on an AEG washing machine indicates a problem with the machine’s configuration or programme setting memory — specifically, the appliance cannot correctly identify the drum size or machine configuration stored in its control board. It’s a moderate fault that will prevent normal operation but is not a safety hazard.
What does this error mean?
E93 signals that the main control board (PCB) has detected a mismatch or corruption in the configuration data that tells the machine what type it is — including drum volume, spin speed capability, and programme options. In plain terms, the machine has lost track of its own settings, usually stored in a small memory chip on the PCB. This typically happens after a power surge, a failed software process, or a faulty/replaced control board that hasn’t been correctly configured.

🔍 Likely causes
🛠️ Step-by-step fix
Power reset: Switch the machine off at the wall socket, leave it unplugged for 10–15 minutes, then plug back in and try a new cycle. This clears temporary software glitches and is always the first step.
Check for a programme reset: Press and hold the Start/Pause button for 5 seconds to cancel any active programme, then select a simple cotton cycle and restart. Confirm the error is persistent and not tied to one programme.
Inspect the power supply: Check your consumer unit for a tripped RCD or circuit breaker. A repeated tripping suggests a wiring issue — do not reset more than once without investigating further.
Check external wiring and plug: Inspect the machine’s power cable and plug for any signs of burn marks, damage, or a loose connection. Replace the fuse in the plug (13A) if it looks discoloured or blown.
If the error persists after a reset, do not attempt to open the machine’s back panel or touch the PCB yourself — diagnosing and reprogramming or replacing a control board requires specialist tools and should be left to a qualified appliance engineer.
Note your machine’s full model number (found inside the door rim on a sticker) before calling an engineer — this is essential as the replacement PCB must be programmed specifically for your model variant.
📞 When to call a professional
If the E93 error returns immediately after a full power reset, or if you’ve recently had a power cut or a PCB replaced, call a qualified appliance repair engineer. Tell them the error code is E93, your full AEG model number, and whether the fault appeared after a power event or a previous repair — this will help them diagnose whether the PCB needs reprogramming or full replacement.
⚖️ Repair or replace?
A PCB repair or replacement on an AEG washing machine typically costs £120–£220 including parts and labour in the UK. If your machine is under 5 years old, repair is almost always worth it. If it’s 8 years or older and the PCB has failed, weigh the repair cost against a new mid-range AEG or equivalent (£450–£700) — replacement may make more financial sense, especially if other components are ageing.
