Error Code: TAP SYMBOL (FLASHING) Difficulty: Moderate
Problem: Water supply issue; water pressure is too low or the inlet hose is blocked/kinked.
How to Fix TAP SYMBOL (FLASHING) Error (Step-by-Step)
- Begin by unplugging your Bosch washer from the electrical outlet to ensure your safety.
- Locate the water supply valves for your washer, typically found behind the machine. Ensure both the hot and cold water valves are turned completely on.
- Carefully pull the washer away from the wall to access the back. Inspect the water inlet hoses for any kinks or sharp bends that could be restricting water flow. Straighten any kinks you find.
- Turn off the water supply valves. Unscrew the inlet hoses from the back of the washer. Inside the connection ports on the washer, you will find small filter screens. Gently remove these screens with needle-nose pliers and clean any debris or sediment from them under running water. Reinstall the screens and reattach the hoses securely.
- If the previous steps do not resolve the issue, the water inlet valve may be faulty and unable to open to allow water into the machine. This part will likely need to be replaced.
- Another possibility is a malfunctioning pressure sensor, which is responsible for detecting the water level inside the washer. If the sensor is faulty, it may incorrectly signal that there is a water supply problem.
- Given the complexity of replacing the water inlet valve or pressure sensor, it is recommended to have a qualified service diagnose and replace the faulty component.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
What to Check Next on This Bosch Washer
Bosch Washer Error TAP SYMBOL (FLASHING): Use the code or symbol as the starting clue, then confirm the actual symptom before ordering parts.
- Unplug the washer before touching wiring, the lock, the pump area, or the control panel.
- Check the door lock, drain filter, inlet supply, and visible harness connections before replacing controls.
- If the code returns during the same part of the cycle, match the repair path to that stage: fill, wash, drain, spin, lock, or control response.
If the issue returns after these checks, match replacement parts to the complete Bosch model number from the appliance tag. The same code can point to different components depending on the exact model and when the failure appears.
