I have the exact same F1 code problem

Primary Control Failure
F then 1 flashes when there is a primary control failure. Replace the machine control assembly.

This was under recall last year.

Telephone Whirlpool at 1-800-253-1301. Whirlpool has acknowledged the F1 fault and will send a serviceman, free parts and labor, to correct the problem concerning the "famous" F1 fault. This is even for washers out of warranty! This concerns model WTW6600 series washers.

Tell them that your Whirlpool Cabrio washer has been receiving the F1 error code repeatedly, with the same symptoms as reported by hundreds of other customers online. You were told that there is a recall for this known defect in the control board, and are requesting that Whirlpool fix the problem including parts & labor.

Be sure to get the authorization code from them so the service person cannot argue about costs.

Basically - this is a problem (faulty chip) on the main controller board of the unit... and the entire board must be replaced with the updated version.

Give the warranty a try (even if it is out of warranty)
