How to Setup a Free Wash

The complimentary (free) wash promotion provides a free wash when redeemed. Like the discount, this promotion can be configured for redemption by a code, paper coupon or token. The complimentary wash can also be set with a schedule to limit the days and/or hours when it can be used.

 When a complimentary (free) wash promotion is redeemed, the customer need not select a wash, as the associated wash will be automatically activated. If added services are enabled, customers will be allowed to purchase these services by adding payment.

The process for setting up a free wash is:

  1. Set up a free wash through the Promotions function of the Sierra management system.
  2. Download all devices.
  3. If using a coupon for redemption, you will need to program your bill acceptor to accept coupons.
  4. If a token is chosen as the redemption method, you will need to program the coin acceptor to accept that token type.
