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.

Water Inlet Valve

OEM: 00263086

Water Inlet Valve for Bosch & Siemens Dishwashers If your dishwasher isn't filling with water properly or is leaking around the inlet area, a faulty water inlet valve is likely the culprit. Over time, these valves wear out and lose their ability to control water flow effectively, leaving you with poor wash results or water damage. This genuine OEM part, reference 00263086, is designed specifically for Bosch and Siemens dishwashers and restores proper water intake function. Replacing it is straightforward enough for a confident DIYer, with an installation difficulty rating of just 2 out of 10. When fitting the new valve, remember to turn off both the water supply and electrical power to your appliance first. This simple precaution makes the job safer and prevents accidental flooding. The valve itself typically sits behind the kick plate at the front of your dishwasher, so access is relatively easy. Before ordering, take a moment to verify your dishwasher's E-Nr model number, which you'll find on the inside of the door frame. This ensures you're getting the correct part for your specific machine and avoids any compatibility issues.

Frequently Asked Questions

What does the E06 error mean on a Bosch dishwasher?↓
Your Bosch dishwasher is displaying the E06 error code on its control panel, which means the appliance's safety system has been triggered. This occurs when the Aquastop feature detects a problem with your water inlet valve or the safety hose that supplies water to the machine. The Aquastop is a clever safety mechanism designed to prevent flooding by cutting off the water supply when it senses an issue, so seeing this error is actually your dishwasher working as intended to protect your home. The good news is that E06 faults are often straightforward to resolve, and many homeowners find they can fix the problem themselves without calling out an engineer. The most common culprits are either the Aquastop safety inlet hose, which may have become kinked or damaged, or the water inlet valve itself, which could be stuck or faulty. Both components are relatively accessible and replaceable if you're comfortable working on your appliance. Before you panic about repair costs, it's worth checking whether the hose is simply twisted or blocked, and whether the inlet valve connections are secure. In many cases, a simple adjustment or cleaning restores normal operation.
Can I fix the E06 error myself?↓
