Problem summary

Water pooling or dripping from underneath your Nordmende freestanding dishwasher is a sign that water is escaping where it shouldn't. This isn't usually a simple fix and needs prompt attention, as standing water can damage your kitchen flooring and cupboards.

Likely causes

Based on 91 similar faults we've attended, the most common causes are:

Door seal degradation (around 13% of cases)
The rubber gasket that seals the door can perish, warp, or collect debris over time. Even small damage lets water escape during the wash cycle.

Door lock mechanism failure (around 4% of cases)
If the door lock isn't engaging properly, the door won't seal tight, and water leaks out underneath.

Printed circuit board (PCB) fault (around 4% of cases)
Electrical failures can prevent the door latch from engaging or cause valve malfunctions that allow water to escape.

Tub or internal cavity leak
Less common, but internal cracks or seal failures inside the wash chamber itself can allow water to weep into the base of the machine.

In some cases, water reaches sensitive electrical components like the antiflood microswitch, which can create safety hazards.

Why this needs an engineer

The door seal, lock mechanism, and PCB all involve electrical or mechanical components that sit in contact with water. Accessing or replacing them safely requires:

If the leak has already reached the base or internal cavity, there's also a risk of damage to the motor, wiring loom, or microswitch—all of which require specialist diagnosis.

When to call SMC Services

Contact a qualified engineer as soon as you notice water underneath the dishwasher. Do not continue using it, as prolonged leaks can damage kitchen cabinetry and create electrical hazards.

If you're in Northern Ireland, SMC Services can usually book a repair within 2-3 working days.

Step by step

  1. Stop using the dishwasher immediately. Do not run another cycle. Continuing to use a leaking machine risks further damage to internal components and your kitchen.
  2. Check for visible pooling or dampness. Look underneath and around the base of the machine. Note whether water appears during standing time or only during a wash cycle—this detail helps the engineer diagnose faster.
  3. Isolate the machine from the mains. Switch off the wall socket or circuit breaker supplying the dishwasher. Do not attempt to inspect internal parts while plugged in.
  4. Call a qualified engineer. Door seals, locks, PCBs, and internal tub leaks all require specialist tools and knowledge to diagnose and repair safely. An engineer will identify the exact fault and advise whether repair is viable.

Frequently asked questions

Can I just replace the door seal myself?
While the door seal is the most common culprit, you'll need to confirm that's actually the fault first. An engineer will inspect the door, its alignment, and the lock mechanism, as a faulty lock or PCB can cause the same symptom. Replacing the wrong part wastes time and money.
Is it safe to keep using the dishwasher while it leaks?
No. Water pooling underneath can damage your flooring, rot cabinetry, and create a slip hazard. More importantly, if water reaches electrical components, it becomes a safety risk. Stop using it and call an engineer.
What if water has seeped into the base?
This complicates diagnosis significantly. Water can damage the motor, control board, and safety switches. An engineer will need to assess whether the machine can be dried and repaired or if the damage is too extensive.
How much does a typical repair cost?
That depends entirely on what's causing the leak. A door seal replacement is relatively affordable; a PCB fault or motor damage is much more costly. An engineer will give you a diagnosis and quote before proceeding.
Could this be a blocked drain?
A blocked drain usually causes water to back up inside the dishwasher during the cycle, not leak from underneath. If water is pooling below, it's almost certainly a seal, lock, or internal component failure.
