An overheating washer is a sign that something is not working properly. Your washer may be hot to the touch or produce a burning smell. Also, your clothes may come out of the water feeling unusually hot. The following could be the culprits:
Sometimes there is a simple explanation as to why your washer feels unusually hot. If you are using an older machine, the cold water valve could have been accidentally connected to the hot water tap, making clothes hot after rinsing when they should be cold. Check this out and eliminate it before you proceed to look at other possible causes.
This is the most common cause of overheating washers. The thermostat is located deep at the bottom of your washer. To reach it you'll have to practically dismantle your washing machine. Unless you are very handy, you are advised to consult a washer repair technician. Replacing the thermostat involves tinkering with electricity. Wiring the electrical parts can be quite tricky for a layman. Unless you're sure of what you are doing, leave this work to a qualified professional.
Drive belt or Drive Motor Pulley
Some washers operate using a pulley and a belt. A worn drive motor pulley and belt will cause overheating. Check and replace them if worn. The belt could also be too tight resulting in excessive tension and overheating. You will need to loosen it.
The motor could be damaged as a result of power surges or a faulty pulley. If the drive motor is worn or rusted, it will cause excessive friction on the pulley belt, leading to overheating. Replacing the drive motor can be dangerous as you could get an electric shock trying to fix it yourself. Call a qualified technician instead. If you have an older model washer, a burnt out power motor could be behind the overheating. You will need to have it replaced.
An object could be lodged in the pump, causing it to jam and making the motor to overheat.
Overloading your washer can stress parts. The drive belt, in particular, will be under great pressure and is likely to wear out faster. You are advised to stick to the manufacturer's recommended load.
Washer repair is not for the fainthearted, especially where it involves electricity. To avoid wasting your money and endangering your life, get a proper diagnosis of the problem. After that, you are advised to hire the services of a qualified washer repair technician.
