If your Bosch Water Heater doesn't ignite, and the pilot flame is slow to light or the red LED flashes, it could be due to flat or incorrectly fitted batteries, or the switch is set to Off. To resolve this, check the position of the batteries and refit or replace them. If the batteries are flat, replace them.
