What it is
The Viessmann DHW cylinder loading pump head is a circulation pump motor used on the domestic hot water loading circuit of Vitodens storage combi appliances. It is the pump head (motor) component, identified by Viessmann part number 7827391. Its function is to circulate primary water through the DHW cylinder loading circuit so the stored cylinder can be reheated.
Signs this part needs replacing
- Domestic hot water runs cold or the cylinder does not reheat as expected
- The loading circuit pump is silent when it should be running
- Boiler reports a pump or circulation fault and locks out
- The pump head runs hot, hums loudly or is noticeably noisier than normal
- Intermittent DHW performance with the pump cutting in and out
Before you order
- Match your appliance model and serial number against the fits list above
- Confirm the part number on the existing pump head is 7827391
- Check your appliance is the storage combi variant in the list, not a different Vitodens range
- Confirm whether the pump head alone is the correct item for the fault found
