What it is
The FLOW SWITCH VK332M is a Viessmann flow switch, supplied under part number 7828795. It is used on Vitodens 200-W appliances in the B2HA and WB2B ranges, where it detects water flow through the circuit and signals the boiler to respond to demand. It is a service component rather than a setting or accessory, so correct model identification is essential before ordering.
Signs this part needs replacing
- No hot water production when a tap is opened, with the boiler failing to respond to demand
- Domestic hot water demand is recognised intermittently, causing fluctuating or interrupted hot water
- The boiler does not fire or modulate as expected during a draw-off
- Flow-related fault indication on the appliance controls during hot water operation
Before you order
- Confirm the appliance model and serial number against the fitment list above
- Check whether the boiler is a Vitodens 200-W B2HA or WB2B variant, as fitment is listed by serial number
- Compare the existing flow switch and its part number with the details given here before removal
- Isolate the appliance and follow Viessmann servicing instructions when replacing the component
