Miele Dishwasher F15 Error Code
What it means
The dishwasher water inlet is blocked or restricted.
Try this first
- Open the water faucet fully.
- If the inlet filter is dirty, switch the dishwasher off, unplug it, close the faucet, remove the water-intake-valve filter and seal, rinse the filter, then reinstall the filter and seal correctly before reconnecting.
- Open the faucet slowly after reassembly and tighten the connection if it leaks.
- Remove any kinks or loops from the water inlet hose; replace a damaged hose rather than continuing to use it.
- Miele specifies that flow pressure below 7.25 psi (0.5 bar) requires attention from the facility manager or a plumber.
- If the fault continues, arrange Miele service.
