whirlpool dishwasher idp 100 ix

i purchased a brand new whirlpool idp 100 ix dishwasher from the store in mid 2017, since then every year and a half roughly the motor had to be replaced. the cost of the motor is around R2600.00 and whirlpool does not give guarantees on the motors even though they are replaced by there own technicians and original brand new motors. i have complaint about this and is forced to purchase a new dishwasher. FYI whirlpool is a ******* please be careful when purchasing this product and consider you would most likely have to replace the motor every second year.
