Common symptoms this part fixes

Before you buy — quick checklist

  • Confirm your existing element is rated 5.5KW / 5500W at 240V before ordering
  • Verify your heater housing accepts M7-threaded elements — check your existing element or housing label
  • Confirm your heater tube accepts a double-bend element configuration — measure or photograph the existing element before removal
  • Check whether your control board or heater assembly uses a single-element or dual-element setup
  • Inspect heater housing for corrosion or cracking — a failed element can sometimes damage the housing, which would also need replacement

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
