Thermador dishwasher lifespan
Thermador dishwashers are designed for 10-15 years of service. Star Sapphire and Emerald models with CrystalDry have slightly different aging patterns — the zeolite cassette may need replacement after 5-7 years, but the machine itself lasts a decade or more.
Always repair
- Drain pump replacement (E24/E25) — most common repair, fraction of new unit cost
- Door latch or hinge — mechanical wear parts
- Water inlet valve — simple swap
- AquaSensor cleaning or replacement
- Spray arm or rack roller replacement
- Rinse aid dispenser
Usually repair
- CrystalDry zeolite cassette — costs less than the price difference between a Sapphire (no CrystalDry) and an Emerald (has CrystalDry)
- Control board — expensive but restores full function on a unit with years of life remaining
- Flow-through heater — specialized part but cost-effective repair
When to replace
Consider replacing if the unit is over 10 years old AND faces a major repair (control board + pump, or multiple concurrent failures). If repair cost exceeds 50% of an equivalent new Thermador model, replacement makes more financial sense. Panel-ready installations add a consideration: your custom panel may not fit a new model if dimensions change — verify before deciding.
Panel-ready factor
If you have a custom cabinetry panel, confirm the replacement model uses the same mounting points and dimensions. Panel and bracket modifications add significant cost to a replacement. This often tips the scale toward repairing the existing unit.
