Main information
Don't self-diagnose it
A dishwasher tripping the RCD is a safety signal. The exact cause can't be worked out from here: only by checking it in person.
Safety first
Unplug the dishwasher if it caused the RCD to trip and don't reconnect it. Don't test anything else: call and a professional electrician will come out to check it.
Next step
An electrician checks the installation and the appliance and diagnoses where the problem is. Until then, we don't know for certain what it is.
Frequently asked questions
Is it common for a dishwasher to trip the RCD?
It can happen, but the exact cause isn't known without checking it; don't reconnect it or test anything yourself, it's better to get it checked.
Does it need an independent circuit like other kitchen appliances?
Recommended, especially if it shares a circuit with other high-consumption appliances.
Could it be a water connection issue rather than electrical?
Possible, but that's also worked out during the check; it's not something you can safely test yourself.
