This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Smeg dishwasher completely dead with no lights
- The problem
- The dishwasher would not start and showed no lights or response when the start button was pressed.
- Likely cause
- The accepted reply points first to a lost mains supply or failed fuse. If the supply is confirmed present, the discussion suggests possible faults with the door latch/door switch, on/off switch, wiring connections, mains filter, or main control module, but no exact fault was confirmed.
- What fixed it
- Begin with basic power-supply checks: confirm the socket or fused spur is live, check the plug or spur fuse, and check for a tripped breaker/RCD. Also make sure the door closes and latches properly. If power is definitely reaching the appliance and it still remains completely dead, further diagnosis should be carried out by a suitably qualified appliance engineer.
- Checks to try
- Check the plug is firmly in the socket
- Test whether the socket is live
- Check whether a fused spur switch is present and switched on
- Inspect the 13A plug fuse if fitted
- Check the fused spur fuse if fitted
- Check the consumer unit for a tripped MCB or RCD
- Make sure the door closes fully and the latch engages
- With the appliance isolated, look for burnt connections, loose wiring, or obvious damage around the mains input area
- Parts or tools mentioned
- 13A plug fuse
- Fused spur fuse
Safety: Do not continue resetting power if the breaker trips again. Isolate the appliance from the mains before removing any panels. Further diagnosis should be carried out by a suitably qualified appliance engineer.

If a Smeg dishwasher is completely dead with no lights at all, start with the simple power-supply checks before suspecting the dishwasher itself.
1. Check the mains supply Make sure the plug is firmly in the socket and the socket is actually live. Try a lamp or kettle in the same socket. If it’s hard-wired, check whether there is a fused spur switch nearby and make sure it hasn’t been switched off.
2. Check the fuse If it has a 13A plug, inspect the plug fuse and replace it with the correct rating if blown. If it’s on a switched fused spur, that fuse can fail too.
3. Check for a tripped breaker Look at your consumer unit/fuse board for a tripped MCB or RCD. If it trips again when you restore power, stop there as that points to an electrical fault.
4. Check the door is closing properly A dishwasher can appear dead if the door latch or door switch isn’t being made properly. Make sure the door closes fully and the latch engages cleanly.
5. Look for signs of power at the control panel If there are still no lights at all after confirming power to the appliance, likely suspects are the on/off switch, wiring connections, mains filter, door switch, or the main control module.
6. Internal checks Isolate the appliance from the mains before removing any panels. Check for burnt connections, loose wiring, or obvious damage around the mains input area.
If the supply is definitely present and it remains completely dead, it will usually need proper electrical testing by a qualified appliance engineer. Any mains-related checks beyond basic fuse/socket checks are best left to a professional.

SAFETY FIRST: READ BEFORE ACTING ON THIS GUIDANCE
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional. Do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts have sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you are not confident testing or working inside the appliance, stop and call a professional.
