Dishwasher noisy: what our engineers find
These figures come from NAC's own repair records: 91 dishwasher jobs our engineers attended for this fault. Here is what they found, what fixed it and what it typically cost.
A noisy dishwasher has no single cause that stands out yet, but engineers sometimes find something caught in one of the pumps, such as broken glass, a stray nut or other debris, which makes it hum, rattle or grind. Now and then the pump that pushes water round the machine has worn out or seized, or the pump that empties it has a broken part that makes the machine judder and click. Engineers also sometimes find water sitting in the base from a leak or a perished hose, which can leave the machine draining constantly and not finishing its cycle.
To track down the cause, an engineer listens to the machine running, checks the filters, spray arms and pumps for blockages, and looks for water in the base. A blockage can usually be cleared there and then. Other fixes include clearing blocked spray arms, sorting out a blocked sink drain or adjusting the machine if the door is catching.
If a pump or hose needs replacing, the part often has to be ordered and fitted at a second visit. The engineer then runs a wash to check the machine is quiet, fills properly and drains away without leaking.

About the price. £104 to £225 is the typical total paid by customers, including parts and VAT: the middle half of what customers paid on 48 of these repairs. Repairs paid for by manufacturers and insurers aren't counted, because that work is charged at contract rates. It's a guide, not a quote. Your engineer confirms a fixed price before any work starts.
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.
- 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.
