Fault

Cause

Remedy

Leak in floor-standing 

DHW cylinder

Flange leaking

Tighten bolts to a torque of 20-25 Nm, working 

diagonally; replace gasket

Pipe connections leaking

Re-seal the connections

Heat-up time too long

Heating  water  temperature  too  low  (measure  at 

floorstanding cylinder flow, not at heat generator)

Increase temperature (adjust controller)

Heating water volume too low (resulting in a wide 

spread, i.e. return temperature too low)

Larger pump

Pay attention to back pressure from parallel 

heating circuits

Internal indirect coil not vented

Vent several times with the pump switched off

Build up of scale on heating surface

Descale heating surface

Cylinder sensor not in sensor well

Check position of cylinder sensor

DHW temperature too low

Thermostat switches off too early 

Thermostat or control unit

Adjust thermostat or increase set temperature 

at control unit

Return temperature too low (e.g. spread too wide) Larger charging pump or increase speed of pump 

in the appliance via the control unit
