Sorry, if off-topic.
I have a two year old electric pressure washer.
Model: Bosch aquatek 100 plus.
I use this every week to wash my car. Last week, the motor was making a lot of sound and the water spray pressure was very low.
So, I took it to the service center where they say the end casing and housing is damaged.
Can this happen? The machine was never abused. Also, they say the pressure washer needs to be serviced every six months. In service, they change some oil of the motor. Is this true, I haven't heard of that from anyone else.
Also, there is nothing mentioned about this service in the service-manual.
