Quick diagnosis table
| What you notice | Likely cause | Check first |
|---|---|---|
| Water at the door | Door seal | Inspect the seal |
| Foam around the door | Hand dishwashing liquid | Use dishwasher detergent |
| Water at the back | Hose connection | Check the hoses |
| Water underneath, machine not filling | Inlet valve or float switch | Stop and call a technician |
Where the leak comes from and the likely cause
- From the door: the door seal is worn or dirty, or the door is not closing properly.
- From the bottom at the front: excess foam from using hand dishwashing liquid.
- From the back: the inlet or drain hose or its connection.
- From underneath, with the machine not filling: the inlet valve or the float safety switch.
- From the sump during the cycle: a cracked tub or a worn pump seal.
Too much foam
Hand dishwashing liquid makes a lot of foam inside a dishwasher, which escapes around the door and looks like a leak. Use a detergent made for dishwashers in the recommended amount.
How we find the source of a leak
- Dry the sump and run a short cycle to watch where the water appears.
- Inspect the door seal, hinges and door latch.
- Check the inlet and drain hoses and their connections.
- Test the inlet valve, the float safety switch and the pump seal.
