Aquastop Safety Inlet Hose

OEM: 00263690

Aquastop Safety Inlet Hose Water leaks around your dishwasher's inlet connection are a sign that the hose has worn out or failed. The Aquastop Safety Inlet Hose (OEM reference 00263690) is the replacement you need to stop pooling water and restore reliable operation to your Bosch or Siemens dishwasher. This safety hose features built-in protection that automatically shuts off water flow if a leak is detected, giving you extra peace of mind against water damage. Over time, hoses can deteriorate from repeated pressure cycles, temperature changes and mineral deposits, making replacement a straightforward maintenance job. Installation difficulty is rated at 2 out of 5, so most confident DIY homeowners can tackle this themselves. When fitting the new hose, make sure both connection points are fully tightened but avoid over-tightening, which can damage the fittings. Give each connection a gentle tug once installed to confirm they're secure. Before ordering, verify your dishwasher's E-Nr model number, which you'll find on the appliance's information label. This ensures complete compatibility and hassle-free fitting.

Door Seal Gasket

OEM: 00263052

Door Seal Gasket for Bosch & Siemens Dishwashers Water pooling around your dishwasher door or leaking onto the kitchen floor is usually a sign that the door seal gasket has worn out. Over time, the rubber deteriorates from repeated heat and moisture exposure, losing its ability to create a watertight seal. Replacing the gasket is a straightforward way to restore your dishwasher's performance and prevent water damage. This genuine OEM gasket (reference 00263052) is designed specifically for Bosch and Siemens models, ensuring a perfect fit and reliable sealing. The installation difficulty rating of 2 means most competent DIY homeowners can tackle this job in under an hour with just basic tools. When fitting the new gasket, remember to clean the door channel thoroughly first, removing any debris or old gasket fragments. This ensures the new seal sits properly and performs optimally. Before ordering, please verify your dishwasher's E-Nr model number, as some variants may require different gasket specifications. You'll typically find this on the appliance's data plate inside the door edge or on the side wall.

Drain Pump

OEM: 00651628

Drain Pump for Bosch and Siemens Dishwashers If your dishwasher is leaving standing water at the bottom or won't drain properly, a faulty drain pump is likely the culprit. Over time, this essential component can wear out or fail completely, preventing water from being expelled during the wash cycle. This genuine OEM drain pump (reference 00651628) is designed for Bosch and Siemens dishwashers and will restore your appliance's drainage function. Installation is straightforward, rated at difficulty level 2, making it an achievable DIY project for most homeowners. When fitting the new pump, remember to unplug your dishwasher and turn off the water supply first. Take a photo of the old pump's wiring connections before removal, so you can easily reconnect the replacement. Most models require you to remove the lower spray arm and filter basket to access the pump beneath the tub. Before ordering, verify your dishwasher's E-Nr model number from the appliance data plate, usually found on the side wall of the cabinet. This ensures complete compatibility with your specific machine.

Frequently Asked Questions

What does the E15 error mean on a Bosch dishwasher?↓
If your Bosch dishwasher display is showing the E15 error code, your appliance has detected water pooling in the base pan beneath the drum. This triggers the Aquastop safety system, which automatically shuts down your dishwasher to prevent water damage to your kitchen floor and electrics. Whilst this might sound alarming, rest assured that thousands of UK homeowners encounter this fault, and many are able to resolve it themselves without calling an engineer. The water accumulation usually stems from one of three common culprits: a faulty Aquastop safety inlet hose that's cracked or disconnected, a worn door seal gasket that's allowing water to escape during the wash cycle, or a blocked drain pump preventing proper water evacuation. Before reaching for your phone to book an expensive repair visit, you can inspect these components yourself. Start by checking underneath your dishwasher for visible water, then examine the rubber door seal for visible damage or debris. These preliminary checks often pinpoint the problem, potentially saving you a substantial repair bill.
Can I fix the E15 error myself?↓
Many E15 faults can be resolved by a competent DIYer. Always disconnect from mains power first. If unsure, consult a qualified engineer.
