Technical details

Baxi Megaflo System Flow Switch Diaphragm Repair Kit Plate 5111141

Product Overview

The Baxi Megaflo System Flow Switch Diaphragm Repair Kit & Plate 5111141 is a replacement hydraulic repair kit designed for use within selected Baxi heating systems.

This kit is designed to restore the operation of the boiler flow switch assembly by replacing worn or damaged internal diaphragm components and associated parts. The flow switch detects water movement within the heating system and helps the boiler control system respond correctly to demand.

Replacing the diaphragm and plate can provide a cost-effective alternative to replacing the complete flow switch assembly when compatible components are required.

ℹ️ Product Condition Options:

This part may be available in New or Refurbished condition. Please check the available options from the dropdown menu.

Technical Insight & Common Failure Symptoms

The flow switch diaphragm operates using changes in water flow and pressure within the hydraulic system. Over time, the diaphragm can become worn, damaged, or less responsive due to continuous operation, affecting the correct activation of the flow switch.

Typical symptoms linked to a faulty flow switch diaphragm include:

  • Boiler failing to recognise water flow
  • Hot water or heating operation becoming intermittent
  • Boiler failing to start when demand is present
  • Reduced boiler performance due to incorrect flow detection
  • Flow switch activation problems
  • Hydraulic-related faults

Replacing worn diaphragm components may help restore correct flow switch operation and reliable boiler performance.

Kit Contents

The kit includes:

  • Flow switch diaphragm
  • Plate component
  • Associated small service components (as supplied)

Please refer to the product images for the exact contents supplied.
