If your Bock Water Heater isn't providing enough hot water, it might be due to several reasons. First, the heater might be too small for your needs, in which case, try reducing how much hot water you use. The temperature setting could also be too low; adjust it as needed. Also, check the display for any error codes and refer to the corresponding tables for guidance.
What to do if the T&P relief valve is gushing hot water in my Bock Water Heater?
If the T&P relief valve on your Bock Water Heater is gushing hot water, it indicates an excessive temperature condition in the tank (greater than 210°F). Lower the temperature setting on the control. Consult the manual for instructions on how to adjust the temperature.
How to troubleshoot a Bock Water Heater when the burner won't light?
If you're unable to light the burner on your Bock Water Heater, start by checking the display for any error codes and refer to the corresponding tables. Air in the gas line could be the problem, in which case you should contact a qualified agency to purge the air from the gas line. Also, a loose wire connection could be the culprit, so contact a qualified agency to inspect the wiring.
Why is the T&P relief valve dripping water on my Bock Water Heater?
If the T&P relief valve on your Bock Water Heater is dripping water, it suggests an excessive pressure condition in the tank (greater than 150 psi). Contact a qualified agency to inspect the water piping system. Expansion tanks are required in closed systems.
What causes rumbling noise in my Bock Water Heater tank and how to fix it?

When the Bock Water Heater displays error code E36, it means that the blocked vent circuit is open. The intake or exhaust vent is blocked, so inspect and clean it. There may be faulty or loose wiring to switches, so check blue and yellow wires. Excessive wind or room draft is creating high pressures.
What does error code E38 mean on my Bock Water Heater?
When the Bock Water Heater displays error code E38, the gas supply pressure is too low. Low supply pressure or undersized piping! see manual. Gas supply is turned off. Pressure drop due to other appliances on the same supply line. Faulty or loose wiring to switch, so check black/yellow wires.
Why is the LED status flashing red on my Bock Water Heater?
If the LED status on your Bock Water Heater is flashing red, it could be due to several reasons. It may indicate an error occurred during start-up. Reset the power to the anode power supply by resetting the power supply to the water heater. The tank might not be filled with water, so disconnect the water heater from the power supply and fill the tank with water. Check the insulation on all connecting harnesses for bare spots and check the connections at the power supply and anode terminals due to poor electrical connection between anode power supply and anode rod. Polarity may be reversed due to incorrect wiring, so refer to the wiring diagram and correct polarity. There may be a defective seal in anode bushing, with the anode rod no longer insulated from the tank. With an ohmmeter, check ...
