Early 70s WH TL Washers
Hi Anthony, First thing to go out, usually the on-off switch, LOL.
No actually the serious problems were when the water pump leaked and took the motor out with it and if the motor shorted the timer was often ruined as well. WH was one of very few washers that mounted the WP directly ON TOP of the motor.
Other big problem was main seal leaks and of coarse lower transmission oil seal leaks which even if small quickly ruined the undersized drive belt WH used on these washers.
One of WHs biggest problems during the late 60s through the 70s is they had parts prices that were usually at least twice what anyone else was charging for similar parts. Because of this we always said the only two repairs that you could justify of these washers was a belt or the inlet valve, even a timer for these washers was over $100 in the 70s and people would not spend that on one.
Don't take all this too seriously as I did see many of these WH washers run for 8-10-12 and even 15 years without any problems and they are fun to watch, they were just never a favorite of the repair industry.
