Dishwashers are a modern convenience that save time and effort in the kitchen, but when they break down, they can disrupt your household routine.

Repairing your dishwasher is often cheaper than replacing it and will extend its lifespan, reducing your environmental impact. In this guide, we’ll explore the costs of repairing a dishwasher, common faults and whether it’s worth repairing or replacing your appliance.

How much does dishwasher repair cost?

The cost of dishwasher repair varies depending on the fault, the brand and the appliance repair specialist’s rates. On average, you can expect to pay between £60 and £150 for minor to moderate repairs. For more significant problems, the cost may be £200 or more.

Factors affecting the cost of dishwasher repair

Several factors influence how much you’ll pay for dishwasher repair:

• Type of fault: Replacing a pump or heating element is relatively straightforward, but repairs like fixing a circuit board are more complex and costly.
• Brand and model: High-end brands like Miele or Siemens often require more expensive replacement parts.
• Age of the appliance: Older models may need harder-to-find parts, increasing repair costs.
• Labour rates: Appliance repair specialists in cities or those with specialised expertise may charge more.
• Warranty: If your dishwasher is still under warranty, some or all of the repair costs may be covered. Always check the details of your warranty before carrying out any repairs.

Common dishwasher faults

Some dishwasher faults are more common than others. These are the most often-reported dishwasher faults and what that usually means for repairs:

Not draining water

If your dishwasher isn’t draining water properly, the issue could be a blocked filter or a faulty pump. Cleaning the filter is a simple fix - just take it out and run it under hot water - but replacing a pump costs around £90 to £150.

Not heating water

A dishwasher that doesn’t heat water may have a faulty heating element or thermostat. Replacing the heating element typically costs £200 to £280, while a thermostat replacement is usually around £80 to £120.

Not taking in any water

This issue is often caused by a faulty inlet valve, which regulates water flow into the dishwasher. Replacing the inlet valve costs between £80 and £120.

Trips the electrics

A dishwasher that trips your electrics may have a problem with the wiring, motor or control board. Circuit board replacement is one of the more expensive repairs, costing £150 to £250.

Suddenly stops working completely 

If your dishwasher has stopped working entirely, the fault could lie with the control board, motor or power supply. Diagnosing and repairing these issues may cost £100 to £250, depending on the specific fault.

How long should a dishwasher last?

On average, a dishwasher lasts 10–12 years. Lifespan depends on the brand, model and how well you maintain it. 

Regular cleaning and proper use can help extend its life. Things you can do to keep your dishwasher in top condition include:

• Keeping it topped up with salt if you live in a hard water area
• Cleaning the filter once a week under hot water
• Using a dishwasher cleaner once a month to clear build-up
• Keeping the door seals clean

It’s worth maintaining your dishwasher, as it could prolong the life of the appliance, saving you money and reducing your impact on the environment. 

Things to consider when deciding whether to repair or replace your dishwasher

When you’re faced with a broken-down dishwasher, it can be easy to think that it’s best to just replace it. But there are plenty of instances where a repair is the most cost-effective and eco-friendly option.

When deciding whether to repair or replace your dishwasher, consider the following:

• Age of the appliance: If your dishwasher is nearing or past its average lifespan, replacement might be the better option. But if it’s less than five years old, it’s worth considering a repair
• Repair cost vs replacement: If the cost of repair exceeds 50% of the price of a new dishwasher, replacement is usually more economical
• Energy efficiency: Newer models often consume less water and electricity, which can reduce running costs over time
• Frequency of breakdowns: If your dishwasher has needed multiple repairs recently, it may be more cost-effective to invest in a new appliance

Can you fix a dishwasher by yourself?

For minor issues, you may be able to repair your dishwasher yourself. Here are some simple fixes you could try:

• Clean the filter: A clogged filter can prevent water from draining. Cleaning it is straightforward and requires no tools - simply run under the hot tap
• Check the hose: Ensure the drain hose isn’t kinked or blocked
• Inspect the door seal: If your dishwasher is leaking, the door seal may need cleaning or adjusting
• Reset the appliance: Consult your user manual for instructions on resetting your dishwasher if it isn’t functioning properly

For more complex issues, such as electrical faults or motor problems, it’s best to call an appliance repair specialist. Attempting a DIY repair could void your warranty or cause further damage, even to yourself if you attempt to repair electrics when you’re not qualified.

Is it worth getting a dishwasher repaired?

Repairing your dishwasher is often worth it if the fault is minor or the appliance is relatively new. For older models or those with significant repair costs, replacing the dishwasher may be a better investment.

But repairing your dishwasher is more environmentally friendly than replacing it, as it reduces waste and the demand for new appliances. When it’s feasible, choosing to repair instead of replace can save you money while minimising your environmental impact.

If your dishwasher is in need of repair, it’s always best to consult a qualified appliance repair specialist. They can diagnose the problem and provide an accurate quote, helping you make an informed decision.
