Vokera High System Water Pressure

Code 32, furnace locks out, pressure gauge may show a high reading.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Overfilled system, Faulty expansion vessel, Stuck filling loop valve, Faulty pressure relief valve

Safety: Allow the system to cool. High pressure can cause hot water discharge.

Check gauge: Confirm the current pressure reading. Anything significantly above the recommended maximum (often 2.5–3.0 bar) indicates excessive pressure.
Release pressure: Bleed a small amount of water from a radiator bleed valve or a drain point into a container until the pressure returns to normal.
Check filling loop: Ensure both filling loop valves are fully closed, and the hose is removed if required by local regulations.
Expansion vessel check: If the pressure rises sharply when heating, the expansion vessel may be flat or have failed. A technician should test, recharge, or replace it.
