Miele Dishwasher F173 Error Code
What it means
The dishwasher water inlet is blocked or restricted, or the available flow pressure is too low.
Try this first
- Open the water faucet.
- If the inlet filter is dirty, switch the dishwasher off, unplug it, close the faucet, remove and rinse the inlet filter, then reinstall the filter and seal correctly before reconnecting.
- Open the faucet slowly after reassembly and tighten the connection if it leaks.
- If water flow is too low, prioritize water intake for the dishwasher and contact the facility manager or a plumber.
- If the fault continues, arrange Miele service.
