As noted here my dishwasher recently died. Exhibiting somewhat atypical decisiveness I used the August 2008 Consumer Reports to select a Whirlpool DU1055XTV to replace it. Whirlpool claims this model is similar to the DU1055XTS which Consumer Reports rated a best buy. I bought the replacement from Sears and it was delivered and installed yesterday. It took 2 people about 40 minutes to install it. Installation didn't look all that complicated since it was replacing an existing dishwasher. Still probably a bit beyond my handyman skills. And by some bizarre quirk in New York state tax law paying for installation made the whole purchase exempt from sales tax.
Initial reports are the new dishwasher compares favorably to the old in cleaning ability. Possibly the old dishwasher hadn't been working too well even before failing completely.
