However, there are also some common issues that homeowners have with their Bosch water heater. These issues can lead to dangerous situations and even expensive repairs. The purpose of this article is to provide a comprehensive guide on how to identify these common issues so that you can be able to solve them quickly and effectively. Let’s check out some of the common problems and their possible solutions.
The temperatures of the flue gases are too high, and they are above 230 f. It is important that you check for any gas leaks near the gas combustion chamber and heat exchanger. Check that the limiter is operating and that all the wires are correctly connected to the control board and the limiter. It is located in the top-right corner of the unit.
Measure the resistance on the wire harness that you are using. It must be between 115 and 120 ohms.
Check the temperature sensor connection of the backflow sensor, because it may be damaged or short circuited. Below the heat exchanger and the ignition electrodes, you can locate the coil.
The outlet temperature sensor should be triggered when the unit is operated at minus 36 f, or when the unit is operated at above 210 f in a situation when it is overheated due to the limescale deposits. Check the sensors and the wiring. You may need to flush the unit to remove the mineral build-up.
Another error code that can be reported by the outlet temperature sensor, but this time the sensor is not sensing the expected output temperature. This is not an error code. Instead, it is a flashing status message that is intended to help you check the wiring. You should also check the gas pressure, because it might be too low. The voltage is too low, and the unit might not have enough grounding.
The primary fan spins slowly while the water heater is running. Check the wiring connections between the fan and the control board. There must be a voltage of 120 vac and the element must be properly grounded.
