Miele dishwashers are often purchased for premium build and quietness, but repair decisions should still be conservative because parts and specialized labor can be expensive. With an expected dishwasher lifespan of about 10 years per Consumer Reports, a repair under the threshold can be a good value when it restores full function and the machine is not too old-especially for a single component like a drain pump, heater, or door seal.
Replacement becomes the safer financial choice when an older unit requires multiple high-cost parts or has leak-related damage, since the risk of recurring failures and water damage rises. Also weigh the convenience factor: frequent service calls can disrupt daily routines more than the repair bill suggests.
The replacement price benchmark is a mid-market dishwasher listing at a major retailer; Miele pricing is often higher, so treat the threshold as a strict cap on repair spending.
