WFW6605MW0 Whirlpool Front Load Washer

We’re looking at the Whirlpool WFW6605MW0 today, and I’ll go through the bevy of error codes for this model. Don’t let the high number of error codes worry you, however. This machine has a lot going on under the hood. As an owner of this machine, I’m sure you already know!

This machine is a newer model with the display built into the door. It’s handy, convenient, and best of all, it’s not subject to spills or, as in the old days, buttons getting stuck thanks to the touchpad.

Another good feature of this machine is the “Load and Go” feature. You can fill the soap dispenser and the machine will use what it needs for every wash without having to add soap for each one separately.

My experience with this model is that it’s dependable and rarely has an issue. But that’s not to say it won’t. I would like to say you’ll never have a problem, but it is a machine after all, and they will break at some point.

That’s why I’m writing this today. That is, to help with troubleshooting via error codes, should the need arise. Remember, if you get stuck on a problem Neli is here to help. Just book an appointment and we’ll be in touch.

Ok, let’s get started…

This list should cover just about any error you might ever see. You can also refer to the Tech Sheet supplied with your machine, but sometimes they come up missing. That’s why these posts are so valuable.

As I said earlier, if you get stuck on a repair or with troubleshooting, we’re always here for you. Book an appointment with us, and together we’ll figure it out.

Till then…
