For my two bits
These Mobile Maid dishwashers are pretty good units for what they are. Long as one has an ample supply of *HOT* water (140F to 160F) and a good detergent results are nothing short of amazing from a vintage unit. For really badly soiled loads unplug and reset the timer for a second main wash...
Besides having to baby that Plastisol liner other niggles would be drying often isn't the best, noise, and as mentioned you really cannot use the top as extra counter space. That is unless you are happy with taking everything off before loading and putting it back afterwards.
Force wise am here to tell you these MM's move some water! You hear china and glassware begging for mercy! *LOL* This dw cleans far better than the more modern Frigidaire portable it replaced. Unlike that unit one rarely finds yibbles especially from glassware/cups loaded in the top racks/in corners.
