Hotpoint dishwasher F02 error code
What F02 means on a Hotpoint dishwasher
Water inlet or supply fault.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
When a Hotpoint dishwasher shows F02, it is telling you there is a fault with the water coming in, either with the supply or with the way the machine takes water in. You will usually notice that the dishwasher is not filling up as it should.
Engineers sometimes find that the valve that lets water into the machine has become blocked with grit, which can stop it filling properly and can even let water creep in when the dishwasher is switched off. This can happen after work has been done on the water supply to your street or home.
An engineer will check how water is reaching the dishwasher and look at the valve that controls it. Where that valve is blocked, they will usually replace it, and they may also recommend a cleaning and descaling treatment to help keep the machine clear. The new valve often has to be ordered in, so it may be fitted at a second visit, after which the engineer will test the dishwasher to make sure it fills properly again.

Before you check anything yourself
- Switch the dishwasher off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
- An error code tells you where to look, not that it's safe to take the dishwasher apart. Don't remove panels or covers to get at the parts it points to: that's an engineer's job.
- If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
