Lamona dishwasher E02 error code
What E02 means on a Lamona dishwasher
Water fill fault: the appliance is not filling.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
On a Lamona dishwasher, the E02 code is a water fill fault. It means the dishwasher is not filling with water. You may notice it is simply not filling, or that a water supply warning is showing.
Engineers sometimes find that the water supply tap under the sink has been turned off, for instance after other plumbing work, and never turned back on. They also sometimes find that the water inlet pipe behind the dishwasher has been crushed or kinked, so water cannot get through even though the machine is trying to fill.
An engineer will usually check that the water supply is turned on and that water can reach the dishwasher. They may listen for the machine trying to let water in, then pull the dishwasher out to look at the inlet pipe along its length. A tap that has been left off just needs turning back on. A pipe that is bent can sometimes be straightened, but if it will not stay flat, the engineer fits a new one. Either way, the engineer runs the dishwasher afterwards to make sure it fills and washes properly.

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.
