HOT WATER TEMPERATURE

FLUCTUATES

1. Unbalanced pressure in waterlines.

The added restriction caused by the Bosch in the hot water system can result in uneven pressures between the cold and the hot. In such cases when mixing cold water at the tap, the lower hot water pressure may be overpowered by a much higher cold water pressure, which may cause the Bosch burners to shut down. Make sure faucet aerators or shower heads are free of minerals. Do not add any flow restrictor to the shower head.

2.Cold water is mixing with the hot water between the Bosch and the outlet.

See 4 under “NO SPARK AT THE PILOT”.

3.Inlet water pressure is erratic due to inadequate supply water pressure or saturated pressure tank on well system.

Check the inlet water pressure. On a private well, raise minimum pressure setting to 40 psi. Confirm that the pressure tank is not water logged.

4.Gas pressure is too low.
