      Having laid some theoretical groundwork in the last webinar, we're going to focus on practical considerations in this one. That means quick n’ dirty techniques for diagnosing sealed system problem using strategically chosen and skillfully interpreted temperature measurements.  Review homework from the first session on 10-2-2017. Home refrigerator practical design and operating rules-of-thumb useful for troubleshooting Practical application exercises Troubleshooting scenario exercise Techniques for making system temperature measurements for determining superheat and subcooling Sealed system diagnosis homework assignment (to be reviewed in the next webinar in this series) If you attended the first webinar in this series, this is your payday! We’re going to apply that keen, penetrating insight you now possess into money- and time-saving shortcuts you can use to diagnose real-world refrigeration systems on service calls.

Maytag Bravos MVWB300WQ2

Recommended Posts

Hello again from a very appreciative Grasshopper!  I am so happy this site is still available for me.  You have all helped me so very much through the years!!

My current issue is with my Maytag Bravos washer (MVWB300WQ2).  Over a year ago this washer was showing the Ld code with each load.  I disconnected the drain hose and removed several bobby pins and a mass of threads from the drain (filter?).  That was quite the "fishing trip" using needle nose pliers.  But, it cleared up the issue for many months!

Now, the washer shows the code again.  Haven't yet attempted to look underneath again for two reasons: 1, sometimes moving the tub vigorously is enough that the cycle will continue; 2, changing the dial to the 'drain and spin' setting and it immediately drains.  I figure that if the drain were clogged again, the drain setting would not immediately work as it does.  

I am very puzzled by this washer's actions and would be very thankful for your assistance in making this washer once again a reliable family asset. :)

I thank you in advance for your assistance!

Beagle  (Becky)

Definitely check the pump again, whoever has the hair accessories in their pockets before washing probably still does... and while you are in the pump, turn the impeller blade with your finger- it should give some resistance, then turn 90 degrees of it's own accord, as if it is working against a magnet (because it is)... if the objects from before damaged the impeller you may only now be experiencing the effects of the damage. This pump doesn't have a filter per se, but a low spot in the washtub that is meant to catch objects- the "vigorously moving" the tub affecting the problem may be a clue that an object or garment is positioned above the drain opening and causing the longer drain time or it could be moving something in the pump impeller housing around allowing it to move spin and pump more freely. 

If the drain hose empties into a stack pipe, I pull it out and visually watch the water drain to make sure the water-flow is forceful and consistent...

Thank you Hiroshi.  The bobby pin user is away at college for her second year.  But, there may have been more already in the washer that are just now in a bad place.  Yes, the low place was where I encountered an asterisk shaped opening above the hose attachment.  I remember spinning the impeller before but had no idea about the magnet control.  Though it does make sense.  One question as I begin moving everything to get to the washer.  If the drain were blocked or the pump damaged, why would changing the washer setting cause it to immediately drain?

Again, thank you so much!

The wash cycles are timed in "increments," so if the drain pump runs too long during a normal wash cycle, the control picks-up on that difference. A "drain only" cycle or switching the wash cycle, or also initiating the drain pump in diagnostics, will reset and/or remove the time requirement the control is "looking" for.

If there is absolutely no impediment to water flow, and the pump is perfect, this would point at a failing control if it consistently shows "Ld" when it should not...

Thank you for answering my question.  Learning is never over-rated.  

I will follow up as soon as we can access and test the pump.

Wow!  So many days have gone by and we are still "living" with this washer's issue.  

We've stopped with the shaking the tub and other such crazy attempts.  It does not always stop a cycle with the Ld code, but when it does, it always shows 12 minutes left in the cycle.

We can sometimes restart the cycle by touching the power, then the start buttons.  

Such a finicky machine!  I guess I don't want to find out that it is the control module.  Way too much moola!  :rolleyes:
