How much are we talking about? It really depends on the brand and the hardware components that failed. A heating element repair might cost anywhere from $50 to $150, while a complete pump and motor replacement might cost more than $300. Yes, appliance repairs can be laborious and expensive. But, all things considered, they are a much better financial investment than purchasing new appliances. Are you, for example, interested in a new built-in dishwasher from a well-known brand like GE? If so, on average, you will have to splurge more than $750 for it.
