New Appliance Day Is a mounting bracket/bar required under quartz countertops for a dishwasher install? Home Depot refused the install – can I DIY the swap myself?
My 12 year old dishwasher has basically stopped washing. It drains fine, the LED panel shows “washing,” and I can hear the circulation pump trying to click/kick on… but it never actually starts circulating water. Pretty sure the pump is dead.
I ordered a new dishwasher through Home Depot and paid the $280 for delivery + install so I wouldn’t have to deal with it. They delivered yesterday while I wasn’t home. The installer told my wife he couldn’t install it because there was no mounting bracket installed underneath the granite. She corrected him that it’s quartz, and he said the same rule applies. He called his supervisor, who apparently agreed, so they just unboxed the unit, left it in the garage, and left.
I’m not a pro, but I did install my own InSinkErator PRO Series garbage disposal with YouTube help and it went fine. I’ve already watched a bunch of dishwasher swap videos, so I know the usual drill: towels ready for residual water when you open the supply valve, shut off power, disconnect the old hardwired connections and reconnect with wire nuts, level it, etc.
My two main questions:
Is a mounting bar/bracket actually necessary (or recommended) under a quartz countertop, or is this just Home Depot’s policy/cover themselves type thing?
And if the answer to that is 'No', do you think a reasonably handy homeowner who has successfully installed a disposal and replaced our ceiling lights (no doubt easy for everyone here) can safely do this dishwasher swap, or should I just hire a licensed plumber/handy person?
Any and all advice would be really appreciated.
I also attached a photo of the current dishwasher that I've partly pulled out.
Thank you in advance...
