Operation and Function
The Bosch AquaStop Hose Assembly is an integral safety feature. Once correctly installed, it continuously monitors for water leaks. In the event of a leak, the AquaStop system is designed to automatically shut off the water supply to the dishwasher, preventing potential water damage to your home. No user intervention is required for its protective function during normal operation.
Maintenance
The Bosch 00674387 AquaStop Hose Assembly requires minimal maintenance.
- Periodically inspect the hose for any visible signs of wear, cracks, or damage.
- Check the connections at both ends for any signs of leaks or corrosion.
- Ensure the hose is not kinked or pinched, which could impede water flow or compromise its integrity.
- If any damage or persistent leaks are observed, the hose assembly should be replaced immediately by a qualified technician.
Troubleshooting
If your dishwasher is not receiving water or if you suspect an issue with the AquaStop hose, consider the following:
- No Water Supply: Ensure the main water supply valve to the dishwasher is fully open. Check if the AquaStop system has activated due to a leak. If activated, the system will prevent water flow. Identify and resolve the leak before resetting or replacing the hose.
- Visible Leaks: If you observe water leaking from the hose or its connections, immediately shut off the water supply and power to the dishwasher. Inspect the connections for tightness. If the hose itself is damaged, it must be replaced.
- Error Codes: Refer to your dishwasher's user manual for specific error codes related to water supply or AquaStop system issues.
For complex issues or if troubleshooting steps do not resolve the problem, contact a certified appliance technician.
