Washer makes clunking noise - stops at 19 minutes-

bearings seam suspect

BALL CHANGE DRUM WASHING MACHINE

try clutch

basket drive and clutch is needed

Does the washer currently work fine aside from the loud clunking noise? Does the clunking noise continue or is it just one loud clunk when it starts to spin? If its just one loud clunk then that is not a problem just ignore it as that is the clutch spring releasing, it probably starting making noise from the grease getting washed off when the washer over filled.
However how did the washer overfill? That issue should be addressed too. Sometimes though, if the tub is not centered from a heavy load the water will spill over the back but its not really an overfill.

see this causes and fix it. God bless you
Tub Bearing If the washer is making a loud noise the tub bearing might be worn out, this is a common problem. The bearing can be replaced.

Clutch If the washer is making a loud noise in the spin cycle, the clutch assembly might be worn out. The clutch assembly makes the connection between the transmission and the inner tub. It is designed to allow the tub to get up to the proper spin speed gradually. As the clutch wears out it may become loud during spin or just after the spin cycle finishes. The clutch is not repairable, if it is loud or not working properly it will need to be replaced.

Drive Belt If the washer is making a loud noise the drive belt might be defective. Over time the drive belt will dry out and start cracking, eventually a piece of the belt can break off resulting in a loud noise whenever the motor is running.

Transmission If the washer is making a loud noise the transmission might be worn out or defective. There are many other more likely causes for noise from a washer. If the noise turns out to be caused by the transmission it may have to be replaced.

Transmission If the washer is making a loud noise the transmission might be worn out or defective. There are many other more likely causes for noise from a washer. If the noise turns out to be caused by the transmission it may have to be replaced.

Drive Motor If the washer is making a loud noise the drive motor bearings may have worn out. Washer motors are normally almost silent when they run. If the motor is run without a belt hooked up to it and it's loud it will have to be replaced.

Water Inlet Valve If the washer is noisy or loud, particularly when the washer is filling, the water inlet valve is at fault. Replace it.

Tub Seal and Bearing Kit If the washer is making a loud noise the tub seal and bearing kit may need to be replaced. This is a common problem and the parts are relatively easy to replace.
Rear Drum with Bearing If the washer is making a loud noise the rear drum with bearing might need to be replace. On this washer the bearing is not sold separately, the entire rear drum will have to be replaced. This is a very involved repair and will require disassembling most of the washer. However, the problem is going to get worse very quickly and so either the drum and bearing will need to be replaced or the washing machine.

Bearing If the washer is making a loud noise the bearing might be worn out. As bearings wear out from friction they gradually get worse and worse until they fail. In the meantime they get louder. If the noise primarily happens during the spin cycle the bearing is likely the problem.
Drive Pulley If the washer is making a loud noise the drive pulley might be worn out, cracked, loose or bent. Remove the drive pulley and inspect it carefully. If it is damaged or defective replace it.

Pulley If the washer is making a loud noise the pump may be worn out, or something might be caught in it. Remove the pump and inspect it for debris. If it is clear and the blades spin freely the problem might be somewhere else.
U-Joint Kit If the washer is making a loud noise the U-Joint may have failed. This is the primary drive mechanism for the agitation motion in this washer. Although this is not a very difficult repair for a DIY'er with some experience, the part is expensive and so it may be worth considering a new washer.

Motor Coupling If the washer is making a loud noise the motor coupling might have failed. The motor coupling connects the motor to the washer transmission. It is designed to fail if the washer is overloaded in order to protect both the motor and transmission

Well it is ethier Belt, Cluch ,motor ,Or transmission. But it does sound like your transmission . The loud clunk is the brake in the gear case ( Trans.). It might have broken off.

You didn't give to much detail about the noise, other then clunking. Does it sound like it's metal against metal? Does it sound hollow? When does the noise take place before, during or after the spin cycle.

The easiest thing to do is check to see if the motor is loose, or if you might have too much slop or slake in the belt, if you do then replace and readjust the belt.

HI thanks for the question. Frigidaire has a life time warranty. on that part .call them. thanks the appliance doc. please rate my answer. thanks.

get a flashlight and see if a foreign object has fallen down through one of the tub holes and is jamming the tub you have to look real close
