Beko DE3861F - Dishwasher worth repair nearly 5 years?

[baggies66]

Hello

I purchased the above dishwasher 4-5 years ago.
I am currently having the following problems and wondered whether these days its worth repairing or just starting again, the dishwasher cost me £200.

It does not switch off via the start/stop button. However the on/off switch does cut the power.

It Hums when on constantly, the timer counts down one minute and then freezes, but the humming persists.

It takes water into the machine, however it pumps the water out straight away.

The Salt warning light is currently flicking on and off. It is not on constant and on checking the salt levels it is full.

Any advice

Thanks
