What it is

The Baxi 5142003 is a condensate tray supplied with a top gasket, listed under the R603 reference. It forms part of the condensate handling arrangement on Baxi appliances, where the tray collects condensate produced during combustion and the gasket seals the top face of the assembly against its mating surface. Both components are specified together under the same manufacturer part number.

Before you order

  • Check the manufacturer part number 5142003 against the appliance documentation before ordering.
  • Confirm the R603 reference matches the unit being worked on.
  • Verify that a top-mounted gasket configuration is correct for the installation.
  • Inspect the existing tray and gasket seating area for damage or debris that would prevent a clean seal.
