Editing Cam timer (section)

==Replacement with electronic controllers==
While still fairly popular, cam timers are mechanical and hence subject to wear and reliability problems. Their reliability record remains good, but there is always some failure rate with mechanical switch contacts.

Electronic controllers have largely replaced cam timers in most applications, primarily to reduce costs and also to maximize product features.

Cam timers don't offer the greater flexibility that CPU-based controllers provide. In addition to offering more wash program variations, a CPU-based washing machine controller can respond to malfunctions, automatically initiate test cycles, reducing manufacturing costs, and provide fault codes in the field, again reducing repair costs. It also provides feedback on real-world failure rates and causes. All of these reduce manufacturing and business costs.
