Immediate steps to keep you safe
Switch off the dishwasher power
For safety and to prevent further operation, unplug the dishwasher or switch it off at the fused spur or consumer unit. This stops the wash cycle and may halt the leak.
Isolate the water supply
Find the isolation valve for the dishwasher (often a small lever or knob under the sink or behind the machine) and turn it off. This will stop water from entering the appliance.
Mop up excess water
Use towels, cloths, or a mop to absorb any standing water on the floor or in cabinets. This helps minimise water damage to your kitchen units and flooring.
Empty the dishwasher
Remove all dishes and cutlery. This reduces weight and makes it easier for our engineer to access internal components if necessary, and prevents items from being damaged.
Common causes
What's usually behind dishwasher leak
Damaged door seal
The rubber seal around the dishwasher door can become worn, cracked, or dislodged over time, leading to water escaping during a wash cycle.
Loose or damaged water inlet hose
The hose that supplies water to your dishwasher can loosen, split, or become kinked, causing leaks. These are often found at the connection points behind the appliance.
Cracked pump seal or drain hose issues
Internal components like the wash pump seal can fail. Additionally, a damaged or improperly fitted drain hose can leak, particularly where it connects to the waste pipe under the sink.
Overfilling due to float switch fault
A faulty float switch, which senses the water level, can cause the dishwasher to overfill and leak from the door or ventilation points.
Detergent overdose or incorrect detergent
Using too much detergent, or a type not suitable for dishwashers, can cause excessive suds that overflow the appliance, mimicking a leak.
Blocked filter or drain
A severely blocked filter or internal drain can prevent water from exiting the dishwasher properly, leading to water backing up and leaking.
How KJ handles this
What happens when we're on-site
- 1
Initial safety check and area assessment
Upon arrival, our engineer will ensure the area is safe and assess the extent of the water damage. They will confirm the power and water supply to the appliance are isolated.
- 2
Visual inspection for leak source
A thorough visual inspection will be carried out to identify obvious signs of water leakage, such as pooling, drips, or dampness around the dishwasher's exterior and connections.
- 3
Diagnostic testing (if safe to power on)
If safe to do so, the engineer may carefully run a short test cycle while observing the internal components and external connections to pinpoint the exact leak location and cause.
- 4
Accessing internal components
The engineer will carefully pull out the dishwasher and remove necessary panels to access internal hoses, pumps, seals, and other parts that could be the source of the leak, depending on the diagnostic findings.
- 5
Diagnosis and written quote provided
Once the cause of the leak is precisely identified, you will receive a clear, written quotation for the necessary repair, detailing parts and labour.
- 6
Professional repair and reassembly
Upon your approval, the engineer will carry out the repair using appropriate tools and parts. They will then reassemble the appliance and conduct a test run to ensure the leak is fully resolved.

FAQ
Frequent questions
My dishwasher is leaking everywhere, should I use it?
No, if your dishwasher is leaking significantly, do not use it. Turn off the power and water immediately to prevent further damage and contact us for assistance.
How quickly can you attend to a leaking dishwasher?
As a dishwasher leak is an emergency, we aim to dispatch a local engineer to you as quickly as possible, often on the same day, to prevent further damage to your property.
What is the £50 diagnostic fee for?
Our fixed £50 diagnostic fee covers the engineer's visit to your property, their time to professionally assess the problem with your dishwasher, and to provide you with a written, no-obligation quote for the repair.
Can I fix a dishwasher leak myself?
Simple issues like a loose hose connection might be manageable. However, many leaks originate from internal components that require specialist knowledge and tools. Attempting complex repairs without experience can worsen the problem or be unsafe.
What kind of damage can a leaking dishwasher cause?
A persistent or significant dishwasher leak can cause considerable damage to kitchen flooring (especially laminate or wood), cabinet carcasses (leading to swelling and mould), and even electrics if water comes into contact with wiring.
What happens if the part needed for my repair isn't stocked?
If a specific part is required and not immediately available, our engineer will secure the situation to prevent further leakage, then source the part and arrange a follow-up visit to complete the repair promptly.
