Squealing is usually belt slip or dry idler roller bearings.
Grinding noises can be a worn main bearing at the back, or the felt front drum slides.
It is a 1996 machine, so probably time to think about replacing it? Diagnosing would involve a full disassembly and check the parts mentioned for wear. This is a UK and Australian model.

If it's working for a while then shutting off, sounds like thermal overload.
I'd recommend replacing the heating element depending on the age of the dryer.
It could also be:
The cable or plug
The interference suppressor
The main drum motor or fan motor
The control panel
The motor starter capacitor
An issue with the wiring, e.g. the wires are worn or melted
It sounds like your tumble dryer may be experiencing some kind of issue with its sensor system or control board. The beeping and stopping and starting could indicate a problem with the sensors that detect moisture levels in the dryer, which can cause the machine to think that the clothes are dry when they are not. This can also cause the condensation to build up on the glass.
Another possibility is a problem with the control board, which can cause the dryer to behave erratically or stop functioning properly. If you have already cleaned out the lint and checked all of the mechanical parts, it may be time to call a professional repair service to diagnose and fix the issue. They will have the tools and expertise to identify the root cause of the problem and repair or replace any damaged parts.
If your Hoover 5kg dryer is not working properly, there are a few potential causes for this problem:
The dryer may not be receiving enough power. Make sure the dryer is plugged in and the outlet is functioning properly.
The dryer's lint filter may be clogged. Clean the lint filter to ensure it is not blocking the air flow.
The dryer's vent may be clogged. Check the vent and clean it if necessary to ensure the air can flow freely.
The dryer's heating element may be damaged. If the heating element is not functioning properly, the dryer will not be able to dry clothes effectively.
If you are unsure how to check for and address these potential causes, you may want to consult the user manual for your Hoover dryer or contact the manufacturer for assistance.
Wow, a late 1980 machine! If it is turning and not heating it probably needs a new heating element, IF you can find one. New ones are more energy efficient and look prettier. They also have sensing programs to stop drying when the clothes are dry and my Whirlpool has a water injector to steam refresh clothes or remove creases before you wear.
