What it is
The Ideal 176603 is a return group kit for Ideal domestic combi boilers. It sits on the return side of the boiler's water circuit, where it manages the path of water coming back from the heating system before it re-enters the heat exchanger. The kit is supplied as a complete return group assembly for the models listed below.
Signs this part needs replacing
- Water weeping or tracking from the return pipework inside the boiler casing
- Boiler losing pressure repeatedly with no visible leak on the system side
- Poor or uneven circulation, with radiators slow to heat on the return side
- Kettling or gurgling noises from the boiler during a heating cycle
- Boiler locking out or showing a low-pressure fault after the return group has been disturbed
Before you order
- Confirm your boiler model and, for Max Combi 26, check the serial number carries the ABS prefix or later
- Match the part number 176603 against the number shown on the existing component or in the boiler manual
- Check whether any seals or gaskets on the return connections need renewing at the same time
