Bosch/Neff warming drawers – 1st chance, 2nd coincidence, 3rd pattern

[twicknix]

I have been attending so many warming drawers at least three of late especially with the run up to Christmas.

I just wanted to find out if anyone happen to share was is the resistance readings for the heating bowl? As I would have thought somewhere between 80 to 100 ohms due to the relatively low powered heating judging from the power rating plate. Despite this, I have cranked up the ohms readings on the multimeter and each settings returned as open circuit.

These are all similar age, 6-8 years old with no heating, red light flashing.

Every bowl tested returned as open circuit; this led me to say get a new warming drawer.

How common is this?

Very common there should be resistance reading on the bowl and yep cheaper to buy a new one

as a quick test i do this

find a 15w mains filiment lamp (25 or 40 would do )

solder 2 wires to the lamp and put 2 small insulated terms on the end

now remove the draw and take off the rear cover with the socket. unplg the wires feeding the draw and plug the lamp wires to it

you can now hold it on the back wall of the appliance and if you turn the appliance on the lamp takes the place of the draw element

if all works ok you can then be certain all is well except the glass element which as we both know is a silly price

I like your thinking on the light bulb, very clever. I will certainly do this and this will help me to confirm which way to go. Thank you

Done a few of these recently no heat due to the module.. old module two screw hole in the centre, new one four holes either side so I had to drill two new holes and the drill bits do not like that metal so melted three drill bits 🙁
