Product review (3 stars): WFW94HEXW and WGD94HEXW
I bought the Whirlpool Duet washer and dryer and two pedestals from a retail store about 6 months ago, and only had two issues with it.

Problem #1

The liquid detergent paper tab under the bottle cap fell out while I was pouring it into the soap dispenser and the washer began over-filling the dispenser with water due to a complete blockage, causing the floor to be completely drenched in water.  My bad

Problem #2

The washer stopped suddenly in the middle of a wash cycle and displayed an error code number:  F08 and E02.  I turned off the power and also reset my circuit breaker to see if this would erase the code, but it didn't.  So I scheduled a service appointment per Whirlpool certified contractor and he hooked up his laptop to the washer and it displayed the error codes again.

The service tech told me that the dispenser motor had failed.  The Dispenser Motor's function is to regulate a moving arm via a cam that allows water to enter the drum.  The arm is suppose to stop after a couple of inches, but when it fails, you will see it tick, jumping past it's preset stops, which cause the washer to trip into an error code.

The part's cost is $60 USD.  Both the parts and labor were covered under Whirlpool's one year warranty.  Something I was unaware of:  The Whirpool warranty offers a thorough cleaning and inspection for both the washer and dryer free of charge.

I had asked the service tech if other owners of the Whirlpool Duet washers had similiar problems and he noted that they do, but like all front-load washers, any make or model, they all have problems.

Would I recommend this washer and dryer?  50-50

LG is suppose to have the highest quality washer and dryers based on customer ratio service issues, but I personally think it's all mumbo jumbo.
