To troubleshoot if the Bosch RDE1821415 water heater & boiler does not start up during the first startup process, follow these steps: 1. Check the water flow rate: Make sure that the filter in the water tap or showerhead is not clogged. If it is, remove the filter and clean or descale it. Also, check if the filter in the corner regulating valve is clogged and get a servicing expert to clean it if necessary. 2. Ensure the desired water temperature is reached: If the water temperature is not reaching the desired level, check if the continuous-flow heater is connected to a thermostatically-controlled water tap. Set the temperature on the continuous-flow heater to "60°". 3. Check the power limit: If the water flow rate is too high or the cold water supply temperature is too low, the power limit may be reached. Reduce the flow rate at the water tap supply. If needed, consult a qualified professional to regulate the flow rate or replace the flow-rate limiter with a smaller one. 4. Verify the fuse and circuit breaker: Check the fuse in the house electrical installation and the appliance's automatic circuit breaker. If necessary, replace the fuse or have the circuit breaker checked by an electrician. 5. Set the power selector switch correctly: Ensure that the power selector switch is set correctly for the appliance. If unsure, consult a servicing expert. 6. Address air sensor detection: If cold water flows out from time to time, it may be due to the air sensor in the appliance detecting air in the water. The heating element momentarily switches off, but the continuous-flow heater automatically resolves the problem and goes back into operation after a few seconds. 7. Winter operation: If the desired water temperature is no longer reached during winter operation, reduce the water flow on the taps until the desired temperature is reached. If the issue persists after following these troubleshooting steps, please contact customer service for further assistance.
If the continuous-flow heater of the Bosch RDE1821415 water heater & boiler is not functioning properly, there are several steps you can take to troubleshoot the issue: 1. Check the water flow rate: Ensure that the filter in the water tap or showerhead is not clogged. If it is, remove the filter and clean or descale it. If the filter in the corner regulating valve is clogged, you may need to contact a servicing expert to clean it. 2. Adjust the water temperature: If the desired water temperature is not reached, check if the continuous-flow heater is connected to a thermostatically-controlled water tap. Set the temperature on the continuous-flow heater to 60°C. 3. Reduce the water flow rate: If the power limit has been reached due to a high water flow rate or low cold water supply temperature, reduce the flow rate at the water tap supply. You can also consult a qualified professional to regulate the flow rate using an angle valve or replace the flow-rate limiter with a smaller one. 4. Check the electrical components: If the water is not sufficiently warm, check if the fuse in the house electrical installation has tripped or blown. You can also have the appliance's automatic circuit breaker checked by an electrician. 5. Set the power selector switch correctly: If the power selector switch is set incorrectly, adjust it to suit the appliance. 6. Address air sensor issues: If cold water flows out from time to time, it may be due to the air sensor in the appliance detecting air in the water. The continuous-flow heater will automatically resolve this issue by momentarily switching off the heating element and then resuming operation. 7. Winter operation: If the desired water temperature is no longer reached during winter operation, reduce the water flow on the taps until the desired temperature is reached. If you have followed these steps and the issue persists, it is recommended to contact customer service for further assistance.
If your Bosch RDE1821415 water heater & boiler does not meet the specified warm water flow or temperature, you can try the following troubleshooting steps: 1. Check if the water flow-rate is too low. This could be due to a clogged filter in the water tap or showerhead. Remove the filter and clean or descale it. 2. If the water flow-rate is still low, check the filter in the corner regulating valve. If it is clogged, you may need to get a servicing expert to clean it. 3. Ensure that the desired water temperature is reached. If the continuous-flow heater is connected to a thermostatically-controlled water tap, set the temperature on the heater to "60°". 4. If the power limit has been reached, the water flow-rate may be too high or the cold water supply temperature may be too low. Reduce the flow-rate at the water tap supply. You can also consult a qualified professional to regulate the flow-rate or replace the flow-rate limiter with a smaller one. 5. Check if the water is not sufficiently warm. This could be due to a tripped/blown fuse in the house electrical installation. Check the fuse and reset it if necessary. If the appliance's automatic circuit breaker has been tripped, have it checked by an electrician. 6. Make sure that the power selector switch is set correctly for the appliance. 7. If cold water flows out from time to time, it could be due to the air sensor in the appliance detecting air in the water. The continuous-flow heater will automatically resolve this issue and resume operation. 8. During winter operation, if the desired water temperature is no longer reached, reduce the water flow on the taps until the desired temperature is reached. 9. If the appliance does not start or no water flows, there may be a power failure or it could be the initial start-up. Open the warm water tap and allow water to flow for at least 1 minute before the appliance begins to heat. If the fault persists, remove the perlator, showerhead, or similar before starting the appliance. If these troubleshooting steps do not resolve the issue, please contact customer service for further assistance.
