My dishwasher shows error code E15 and cuts off the water supply
Home Nura guide — category: Smart Dishwashers
Diagnosis
On many dishwashers, error code E15 commonly means the leak-protection system has tripped: water has been detected in the base tray and the water inlet is shut off. Check your manual to confirm this, then find the source of the leak before restarting.
Possible causes
- Water in the base tray after a leak — the safety float shuts off the inlet and the machine refuses to start.
- Too much foam or rinse aid — suds overflow into the base and trigger the leak detection.
- Door seal or spray arm letting water out — water marks appear around the door or under the machine.
- Dripping inlet hose or connector — dampness is visible at the back or at the water supply valve.
- Stuck base sensor or float — the code stays on although the tray is dry, even after cleaning and drying.
Recommended steps
- 1Switch the dishwasher off, unplug it and turn off the water supply; check the manual to confirm what E15 means on your model.
- 2Remove the dishes and racks, soak up any water in the tub with a sponge, then check the spray arms and the filter.
- 3If you can do it safely, tilt the machine gently as the manual allows to drain the base tray, or leave it to dry overnight.
- 4Check the door seal, the inlet hose and its connectors for damp; tighten visible connectors by hand only.
- 5Use less detergent, avoid regular dish soap, then run a short empty cycle and watch whether the code returns.
- 6If E15 returns or the leak persists, keep the water supply off and the machine unplugged and call a technician or the manufacturer's support.
Repair or replace?
If the base tray fills again even though seals and connectors are intact, the leak comes from an internal part that can be costly to replace. On an older dishwasher, replacing it often beats the cost of repair.

Frequently asked questions
Usually, yes, if the failure shows up during the warranty period and isn't caused by misuse. A product in the Smart Dishwashers category bought new from an authorized retailer normally comes with a manufacturer's warranty: check its length in the manual or on the brand's website. Consumer protection rules also vary by province and territory, so keep your proof of purchase.
If you're still within the store's return window, a return or exchange is usually the fastest fix. After that, the manufacturer's warranty takes over: its customer support can arrange a repair or a replacement. Even outside the warranty, the manufacturer can often repair the device for a fee. Either way, keep your proof of purchase.
Our public methodology lowers the Nura Score /10 of any model in the Smart Dishwashers category whose recurring failures are documented in owner reviews. A model that breaks down too often never tops our rankings, whatever the brand.
Generally, yes. Routine maintenance, such as cleaning, replacing a gasket or recalibrating, is part of normal use and doesn't usually affect your warranty. Irreversible changes to the hardware are what can cause problems. For a product in the Smart Dishwashers category, stick to the steps described in the manufacturer's manual and read the warranty terms before going any further.
When a product fails in its first few months of normal use, the cause is usually a manufacturing defect. Contact the seller or the manufacturer with your proof of purchase and a description of the symptom: for a model in the Smart Dishwashers category that is still under warranty, this is the typical case for a free repair or replacement. Warranty terms vary by brand, so read yours.
