Issaquah Wolf Touch Panel Locked

Touch Panel Locked and Will Not Release

Short answer

A Wolf cooktop showing its lock symbol ignores every pad until the lock is held off: three seconds on current induction and electric tops, five on older CT induction models. The panel also relocks after a power cut and after being left idle. If a dry, clear panel will not release, Summit Cooking Appliance Service, (425) 272-6613, tests the touch control and its supply on the $89 visit.

Two generations, two holds

The lock exists so a sleeve or a wiping cloth cannot switch a zone on, and while it is set, every pad is ignored. How it releases depends on the model. Current Wolf CI induction and CE electric tops lock and unlock with a three-second hold on Lock. Older CT induction tops unlock with a five-second hold on the key symbol, confirmed by two chimes; three chimes is the sound of locking, which takes a three-second hold.

Both lock themselves when left alone, CT tops after five idle minutes and current ones after ten, and both start up locked after a power cut.

Where the installation comes in

A top that keeps coming back locked may be losing power rather than misbehaving. Wolf wants it on a circuit of its own and advises against GFCI protection, which it says may interrupt operation; each interruption puts the panel back in lock. Up in the foothills around Mirrormont or Tiger Mountain, a winter storm that drops the power will relock it. A lock that returns on a calm day points at the supply instead.

When it still will not release

Touch pads read a fingertip through the glass, and water, spray cleaner or a pan resting on the strip can confuse them. Wolf asks for cleaner to go on the cloth, never straight onto the controls. If a dry, clear panel still refuses, the touch control itself is tested.

Before you book

Dry the control strip with a soft cloth and move any pan, lid or utensil resting on or beside it; Wolf asks that hot cookware never sit over the controls.

Hold one fingertip on the lock symbol and keep it there: three seconds on a current Wolf top, five on an older CT induction top, which confirms with two chimes.

If the panel locks itself after a few idle minutes, that is the automatic lock. On current models it can be turned off in the extended options set out in the use and care guide.

Stop there. Whatever sits behind the appliance's own panels, on its gas valves or live inside it is ours to test: call Summit Cooking Appliance Service on (425) 272-6613 and say what you found in the steps above.

Questions

The lock light is out but nothing responds. What then?

Then the lock was not the cause. Check that the cooktop's breaker is on and the strip is dry, and try a single zone with a pan on it. If no pad anywhere on the strip answers, the touch control becomes the suspect. Summit Cooking Appliance Service, (425) 272-6613, reads the supply first on the visit and tests that control after.
