What it is
The Vaillant 010354 is a complete diaphragm for the diverter valve assembly used on Vaillant Ecomax 200 series boilers. It sits within the diverter valve and responds to pressure changes to switch the boiler between domestic hot water and central heating operation. The part is supplied as a complete diaphragm assembly.
Signs this part needs replacing
- No domestic hot water, or hot water only when the heating is already running
- Boiler fails to switch from central heating to hot water when a tap is opened
- Radiators warming when only a hot tap is run
- Fluctuating or inconsistent hot water temperature
- Visible splitting, perishing or distortion of the diaphragm on inspection
Before you order
- Confirm the boiler model and GC number against the fitment list above
- Check the part number on the existing diaphragm or diverter valve assembly
- Inspect the diverter valve body and seals for wear before refitting a new diaphragm
- Confirm whether the full diverter valve assembly, rather than the diaphragm alone, is required
