MHW6630HC1 Maytag Front Load Washer | Error Codes

I know this machine is a little intimidating at first look. But if you have the mechanical aptitude to tackle a repair on this machine, you can save a boatload of money.

Ok, so you don’t have tons of experience with washers. No worries. As long as you know the right end of a screwdriver, we can walk you through any repair.

We’re looking at the Maytag MHW6630HC1 front load washer error codes (shown here on a matching pedestal) today with suggested solutions.

This model is a greatly improved version of past machines from Maytag. They were always reliable, but I think too many people took one look at the machine and instantly thought it was indestructible.

I wish that were the case, but honestly, if you take care of it and don’t overload it, it will last many years without a lot of problems.

It’s when the machine is abused and expected to perform beyond its capabilities that the problems (expensive, by the way) begin to show.

Although this machine is big, once you know how to take it apart and spend time learning about its ability to wash clothes, I think you’ll be impressed.

That said, below are the error codes you’ll find on this machine. They’re self-explanatory and informative. But remember to always consider the error code may not tell you exactly what part is causing the problem.

Instead, consider that the machine diagnostics is very smart and always gets you in the right place. You’ll have to use common sense and your working knowledge of the machine’s process to pinpoint the bad part.
