• Reduced or fluctuating domestic hot water temperature while the heating circuit runs normally
• Domestic hot water running cold or only warming intermittently
• Scale or sludge blocking the plate passages, restricting flow through the domestic hot water side
• Water weeping from the plate pack or its connections
• Poor heat transfer between the primary and domestic hot water circuits

• Confirm the boiler model and GC number against the fit list above
• Check the part number on the existing heat exchanger matches D020116522
• Verify whether the fault lies with the plate heat exchanger or another component in the domestic hot water circuit before ordering
• Isolate and drain down the appliance before removal, following the manufacturer's instructions
