I had dilling harris push button
doors. They had three boards. Timer board, sound board and controller board. It would make sense that everything could be done on one board.
Pros of push button/DH
doors from my perspective:
- customer could select a function without having to turn past one or more functions
- meter box would reset itself so customer was always starting from the beginning
- allowed for adjusting time given for different products
Cons of push button/DH:
- if there is a problem with a/the board you can’t fix it yourself
- more expensive to purchase
I spent a lot of time and money trying to keep the push button meter
doors working. Switched to the rotory dial and glad that I did.
One issue with the rotary switch is customers turning the dial rapidly. Every function will start as the customer turns the switch. I learned an easy fix for this from the forum....wire in timer delay relays at the pump stand.
I used a self serve wash in Maryland last week that had Gin San push button
doors. Worked well. My one experience with Gin San was not good. Did not find them to be knowledgeable or helpful.
Good luck.
