What it is
The FLOW LIMITER E-W-LP 12L RED is a Worcester Bosch flow limiting component used in Greenstar gas appliances. It restricts the volume of water passing through the relevant water circuit so the appliance operates within its designed flow rate. The 12L designation in the part name identifies the limiter variant, and the part is colour marked red.
Signs this part needs replacing
- Hot water flow at taps or outlets is noticeably lower than expected
- Shower performance from the combi drops below what the appliance normally delivers
- The existing limiter is missing, cracked or visibly damaged after service work
- Flow through the appliance is inconsistent between outlets
Before you order
- Confirm the appliance model against the fits list above before ordering
- Check that the fitted limiter is the E-W-LP 12L variant so the replacement matches
- Verify the part number 8737713717 against the reference on the existing component
- Inspect the surrounding water circuit for debris or scale that may have affected the original limiter
