Kenwood ceramicare with standby steam iron keeps switching off

Have you fed it with water

Do you drain the vinegar before turning on the iron and steaming through?

use the following ideas
As with many small appliances, regular maintenance makes a dramatic difference in how trouble free your electric iron will be. Even so, things can happen.
If the iron doesn't heat, make sure power is on to the outlet, check the electrical cord, and check the thermostat (see the Appliance Controls Fix-It Guide) and replace if necessary.
If the iron heats but steams improperly, inspect the soleplate and clean the vents (see below) and flush sediment out of the steam chamber (see below).
If the iron produces too much or too little heat, test the electrical cord . Also test and, if needed, adjust calibration of the thermostat

If the iron does not spray properly, inspect and clean the nozzle (see below).
If the iron leaks or spits, clean the steam vents, nozzle, and tank.
If the iron sticks to fabric, clean or repair the soleplate. If the iron stains fabric, clean the soleplate, clean the tank with a commercial cleaner, and use distilled or filtered water.

God bless you

Kenwood iron the light will not go out new filter in

Cant solve the problem but does anyone know where I can buy a filter in the uk for it or the up todate model no for the filter? please

Blinking red light is a standby phase, its not going to get hot like this. Shake it or just start ironing, the red light will go solid and the plate will heat up. The red light will go off when the plate is hot enough. It will go on again (solid) after a few minutes to keep the plate at the right temperature. If you leave it standing around for a while it will begin blinking again (standby).

These irons are known for malfunctioning though, mine stays in standby and the plate never heats up! Hopefully yours is fine.
