How to Setup a Hidden Wash Package

A hidden wash is a specific wash package that can be assigned to, and is visible only to, account holders at the car wash entry system and not offered for purchase to regular customers. A hidden wash may be assigned to a product-based pre-paid, fleet, or subscription account. A hidden wash may have up to 4 added services assigned to the wash package.

This feature requires the Sierra management system to have a minimum version of 1.52.

 The process for setting up a hidden wash package is: 

  1. Setup a product-based account through Accounts/Accounts function of the Sierra management system.
  2. Setup a Product through the Setup function of the Sierra management system.
  3. Add the wash package through the Wash Dispensing function of the device profile.
  4. Download the device profile.

To setup a new pre-paid account program, go to the Accounts tab, then select Programs from the left frame.

Select Pre-paid account from the drop-down menu below the table and click Add New Account Program. The Edit Account screen will be displayed.

To setup a product-based account, follow the directions, below.

  1. Enter the name of the account program.

  1.  Select the relay pattern that the wash equipment requires to deliver the desired wash package. Normally, only one relay output is turned on for each wash package. The alternate relay pattern is used to notify the wash controller of a change that’s required in the wash service. A typical use would be to set a “hybrid” wash for either a “touch free” or “soft touch” wash delivery. When an alternate relay pattern is enabled, a customer option message must also be set in the User Interface set-up.
