Frequently Asked Questions
What does the E16 error mean on a Siemens dishwasher?↓
You've likely noticed water pooling at the base of your Siemens dishwasher, or perhaps you've spotted moisture inside the drum even though the machine is switched off. That E16 error code appearing on your display is your dishwasher's way of alerting you to a water inlet problem. Specifically, it means water is leaking into the appliance when it should be completely sealed and dry.
The good news is that E16 faults are often straightforward to diagnose and frequently fixable without calling out an expensive engineer. In the vast majority of cases, the culprit is a faulty water inlet valve – the component responsible for controlling water flow into your machine. This valve can wear out over time or develop internal damage that prevents it from closing properly.
Before you panic about repair costs, it's worth checking a few simple things yourself. Inspect the inlet hose connections at the back of your dishwasher for any visible cracks or loose fittings. More often than not, however, you'll need to replace the inlet valve itself. This is a reasonably accessible repair that many homeowners tackle themselves with basic tools and a bit of patience.
Can I fix the E16 error myself?↓
Many E16 faults can be resolved by a competent DIYer. Always disconnect from mains power first. If unsure, consult a qualified engineer.
