The same DC07 has come back for another repair. I did say to my customer that once the cyclone is blocked it can put strain on the motor, but we agreed before changing the motor we would just clean the cyclone out first. the suction is brilliant. Better than your average DC07, cyclone is clear and the motor cuts out after about 4 minutes.
Can the fault be just the thermal cut out unit, as opposed to the motor. the suction is that good that its is quite an effort to glide over the carpet. Also, the filters are good. ive tried a new post motor filter and the pre motor filter looks fine, certainly seen a lot worse without the fault.
Its clearly a motor fault, but wondering if it might be just the thermal cut out.
