The only thing worse than having to pay for premature appliance replacement is.. the process of actually replacing them.
Across different homes, different appliances, different brands, and different vendors it is always a disaster.
Dishwashers especially since they touch cabinetry, plumbing, and electrical.
I would pay an "A Team" premium to have an entire squad come deliver and do all work to accommodate installation.
I've had just about everything go wrong:
* fridge installer taking 3 tries to send enough guys to lift a giant fridge up stairs (2, then 2 again, then finally 4)
* Finding out my condo counters are ADA accessible special short height that is 3/8 of an inch too short to fit 90% of DWs without carpentry work
* DW installer leaving, wanting a plumber to replace water line before continuing
* DW installer leaving, wanting electrician to do hardwire/outlet work before continuing
* DW repair guy leaving, because he couldn't figure how to pull the dishwasher clear of a tile floor ridge
* DW repair guy disconnecting my kitchen sink water line, breaking a part making it unusable unless I made it to the hardware store across town closing in 10 minutes
* Plumber knocking DW door off the spring hinge mechanism so it just drops like a rock now
Basically theres 3-5 different specialists that all need each others work done in a particular order and possibly to do re-work after one of the others breaks something, every every time.
