Frequently Asked Questions

What does the C2 error mean on a AEG dishwasher?↓
You've noticed your AEG dishwasher's programme indicator flashing and the cycle has stopped mid-way: this is the C2 error code, and it's telling you that water isn't draining from your machine as it should. Whilst this might sound concerning, the good news is that many C2 faults can be resolved without calling out an engineer, saving you both time and money. The most common culprits behind this error are relatively straightforward to check yourself. Start by inspecting the drain hose for kinks, blockages or damage, as this is often where debris becomes trapped. The drain pump filter is another frequent offender: this small component catches food particles and can become clogged over time. You should also examine the spray arms to ensure they're rotating freely, as a jammed arm can interrupt the drainage cycle. Less commonly, a faulty drain pump or blocked spray arm holes might be responsible. Before you panic, try these simple checks first. In many cases, you'll identify and fix the problem yourself. If these initial troubleshooting steps don't resolve your C2 error, then professional support may be necessary.
