My Vaillant Turbomax 282/1E No Hot water when hot water tap is turned on?
When I turn the hot water tap on there is no ignition signal to the boiler to switch boiler on. Is there a flow switch or pressure sensing valve on the hot water supply line to switch on the ignition circuit?
if its the greeen switch order a new one easy to replace. if its the new black type try to release the tension screw,and push it up gently as it may have simply dropped slightly.

there's a flow switch green or black colour inside the boiler on the diverter valve download the manual from vailant site most likely thats the cause very common on vailants
