Re filter for top loader. Most have a removable section at the top of the agitator column. Grap the top section of the column in both hands, twit and pull upward.
Quote:Most washing machines collect lint during the wash cycle and send it down the drain during the drain cycle.
If your machine is a Maytag, though, it may be different. Most Maytag washing machines collect lint in the center tube of the agitator. You need to lift out that tube and clean it periodically.
Other machines have a lint filter near the top of the tub, which you need to slide out, clean off, and reinsert.

Point at the parts towards the top of the agitator.
You will see a Bolt That bolt needs to be removed to to get the agitator off. Your underwire will be underneath the agitator.
If you can make a tool in the right length and thickness it may be possible to scrape the underwire out from under the agitator. I doubt it though. Our old waher was a hoover and I removed the agitator several time for similar reason. It was quite simple. Remove the fabric softner cup remove the water seal remove the 14 mm hex head bolt. (required a long socket extension.) Lift the agitator out, clean out the tub, replace everything.
