Ideal Flow Switch 10 Section 175136

The Ideal 175136 is a flow switch supplied for Ideal Commercial Vroy GT 10SE boilers built with a 10-section heat exchanger. It sits in the water circuit and confirms that circulation is present, signalling the control board that it is safe for the burner to run. The same component is listed under the alternative number 88024715.

• The boiler fires briefly then locks out because no flow signal reaches the control board
• Circulation is present at the pump but the appliance still refuses to run
• Repeated lockouts or fault codes on start-up that clear and then return
• Intermittent operation, with the boiler running normally on some calls for heat and failing on others
• The switch fails to change state when flow is proven at the pipework, indicating a stuck or worn internal mechanism

• Confirm the appliance model and serial number, as the flow switch is matched to the 10-section Vroy GT 10SE build
• Check the existing part against the alternative number 88024715 to be sure the correct item is being replaced
• Inspect the sealing washers and connections at the switch housing and renew them if they show signs of hardening or leakage
• Work on the water circuit should be carried out by a competent engineer, with the appliance isolated and drained as required
