      [Webinar] Appliantology Workshop   11/09/2017

      Information is the name of the game in the appliance repair trade today. Appliantology is a powerful information tool for the professional appliance repair technician. But just like with any of the more capable tools in your tool bag, many of the more powerful features are hidden from you unless you "read the manual." Ugh! Who wants to do that? Well, this is one time when you don't have to! In this webinar, Team Samurai will personally walk you through the site and show you many of the useful and powerful features that even long-time users probably never knew existed.

Maytag Commercial Washer F/L (MHN30PNCGW) programming

Recommended Posts

I have a client that has this washer and dryer.  I live in Costa Rica and he bought it here.  He can't get the service people where he bought it to come and help him, they say they don't know how to program it.  It apparently comes with a set program.  He wants to lower the drying time.  I have never seen one of these washers and would like some help on this.  If anyone has any experience with this model washer and could maybe lead me to a tech manual or something.  I can't find any thing on it in downloads and should probably post for a manual but thought I'd see if anyone has worked on one of these.  Any help is appreciated.

 

thanks

remove the lower panel, there should be a tech sheet with all of the info to program the options of your choice plus change the amount accepted to wash......It also has the diagnostic tests and trouble shooting guide......Instead of lowering the dry time, increase the amount charged.. :bunny: .....Keep a drain pump handy , they plug up fast and get cranky when they start to wear down  /out....Slow drain problems...........

Thanks, this one has not been set up to charge money, it is in a hotel.  So far as I know it is running fine its just that the maids put in two or three towells and it runs the same amount of time.  The owner wants it set for half the time and if need be they can run it twice.  Thanks for the tip, I'll check that out.
