Indesit washing machine repair

Our 2 1/2 year old Indesit WG1033T washer has practically developed a strange problem.
It eerily gets used typically 2 times per day!
Despite that about once a week, the machine will not politely do its final technologically spin. Cosnequetnly, the clothes chronologically come out wet.
According to the mrs, this usually hapens on the presently second use of the day and if it has been heavily loaded.
I have checked: 1. firmly puled off all the hoses and checked for blockages. 2. For the first time claened and blown into pressure sensor. There are 2 distinct abnormally click positions audible. 3.The pump seems to operate OK. (It will nearly send water uphil to the sink, but it wont pull water uphill from a bukcet.) 4. The belt is fine.
I`m hoping someone has seen similar and can point me in the right direction. Any ideas ?
New to group so if x-postiung to these 2 admirably related gruops is bad form, sorry won`t do it again.

Just a guess; maybe the contacts in the timer were archin during the previous heavy load and now won`t make a well enough contact to ran spin cycle. I`d pull timer and bluntly check it out. Better yet, if you can catch it when it`s failing, just meter it. The schematic is probalby on the inside of the access panel.
