A Speed Queen TC5 that growls, grinds or clunks is a commercial-grade agitator washer, and a certain amount of noise is part of its character, so the first job is to separate the normal from the worrying. The TC5 is a 3.2 cubic foot top-loader with a traditional agitator and a real transmission, called Classic Clean, that gives an aggressive 210-degree stroke. It is built for heavily soiled work clothes and uses a full tub of water.
The checks in more detail
Because its wash action is driven by a transmission rather than a quiet electronic motor, it makes more sound than a modern high-efficiency washer, a steady working hum and the rhythmic motion of the agitator. What is not normal is a new, harsh noise. Run the washer empty with some water and listen. A grinding that comes while the water drains points to the drain pump, where a coin, button or hair clip can catch.
A squeal or a slap that rises as the agitator starts often points to the drive belt, which can slip or wear; the belt is a modest, accessible part on this washer. A heavy clunk at the end of each stroke may point to a worn transmission part or a loose agitator, so lift the agitator out and look at its seat, and make sure it is correctly fitted. A bang on the spin suggests balance, a lopsided load or an unlevel stand.
Check the simple things first: remove clothes, look for coins under the agitator, level the washer and avoid overloading, since a full tub of heavy clothes stresses the drive. With the washer unplugged, turn the basket by hand and feel for roughness in the bearings. A worn belt, a worn transmission or a bearing needs a technician or a competent repair with Speed Queen parts. With a 5-year warranty, check your purchase date. Quote TC5003WN and the serial number.
