What is actually happening
An integrated dishwasher door carries the weight of a cupboard door on its hinges and springs, and those take a lot of use. When a hinge spring or cable breaks the door drops slightly, stops meeting the catch square, and will not latch — which the machine reads as an open door and refuses to run.
The White Knight fault codes that point at this
A White Knight dishwasher will usually tell you what it thinks is wrong before anyone opens it up. These are the codes we hold for this make that relate to door will not close:
- F03 — The dishwasher isn't getting the water it expects, or it can't measure the water going in, so it has stopped the cycle.
- F04 — The dishwasher has asked for water but the flow meter isn't seeing any coming in, so it stops rather than run dry.
If yours is showing one of those, that is a much shorter conversation than a general fault — tell us the code when you book and the engineer can often carry the part.
The usual causes on a White Knight dishwasher
- A broken door hinge spring or cable on an integrated machine
- A misaligned or dropped cupboard door front
- A worn or broken door catch
- Racks or a tall item fouling the door as it closes
- The machine not sitting level in the housing
What you can safely check yourself
- Pull the racks out and check nothing is protruding to catch the door
- Watch the door as it closes — a door that falls the last few inches rather than closing smoothly has a broken spring
- Check the cupboard front is still square on its fixings

Common questions
Why is my White Knight dishwasher door will not close?
The door will not latch shut, so no cycle can be started. An integrated dishwasher door carries the weight of a cupboard door on its hinges and springs, and those take a lot of use. When a hinge spring or cable breaks the door drops slightly, stops meeting the catch square, and will not latch — which the machine reads as an open door and refuses to run.
Can I fix a White Knight dishwasher door will not close myself?
Pull the racks out and check nothing is protruding to catch the door. Watch the door as it closes — a door that falls the last few inches rather than closing smoothly has a broken spring. Check the cupboard front is still square on its fixings. Beyond those checks this one normally needs an engineer.
