A bit worried this might turn into something more serious! A couple of times during use, the pilot light 'machine ready' has gone off and the machine's stopped working (the on/off main switch stays illuminated). Both times this has happened, the water tank has been empty and the issue's gone away when the tank is refilled. I've also noticed that the water tank pilot light isn't coming on at all. I can only assume that the're something wrong with the water availability sensing and the machine's cutting out for safety reasons. Any thoughts? BTW, the machine's a bit over 3 years old and has had the OPV mod.

Bit of an update; thought the LED might have gone, so swapped the bulbs from the two pilot lights for a test and the tank light still works

Another update… The tank pilot light flickers rapidly when the machine is turned on, then goes out a short while after. Also, the steam pressure is way down, despite the gauge sitting at 1.5bar

It seems to me that there might be an issue with the tank low water sensing…this could simply be down to float positioning, the float system is in a little tubular section at the bottom of the tank. Confirm it's moving OK, doesn't have a leak and that the sensor below has not come loose. As for the gauge sitting at 1.5 bar it could be: * gauge is broken, does it move from 0 to pressure when first turned on and drop to 0 when machine is cold? * There is a blockage in the steam tip, usually the tip has to be removed to clear/clean it fully * there is a blockage in the steam arm or steam valve (disassemble and clear) Usually this sort of problem is improper cleaning/usage, or limescale. Taking videos of the problems and issues can help, they should be uploaded to Youtube as unlisted and the link pasted here. The videos should be the best resolution you can do and show as much of the front panel as possible.

Thanks for the comprehensive reply Dave I think the steam pressure could be coincidental, it looks like one of the nozzles was blocked (first time ever). I've cleared this and will recheck in the morning. The gauge seems to be operating ok, it's back down to zero now the machine's cold. I had already checked the float and sensor. Both looked ok, but I'll check again now that I know what to look out for.

Float & sensor seem to be working fine. I've taken some videos (in sequence) of the start up. https://youtube.com/shorts/pGHO7cgXU24?si=jdVIMsU2m9UEMf9-

Lelit Mara X odd behaviour

eduk

DavecUK The flashing of the water light looks too fast to be a low water indication. Remove the float and see what happens.

I tried removing the float, no difference. The light flasher during warm-up, but then stays off, even when the tank is low.

As far as I recall, this light would always be on solid, except for when the water is low, when it blinks slowly & continuously.

Doram I think the light that flashes on and off until ready is the temp light (on the left), but the issue in the videos is with the water light indicator (should be solid when there is water in the tank, or flash on and off when there isn’t. In the videos it’s flickering or off even when there is water in the machine and it’s otherwise working correctly).

That’s pretty much sums it up

eduk

Doram Failing that, I would try to send a video of the flickering light to Lelit. My impression is that they were quite responsive and helpful when contacted. Would be great to hear if you managed to find a solution.

That’s the next step, I’ll keep you posted!

@Doram @DavecUK

The response back from Lelit was:

‘It seems that the issue is due to the LED (code 4000026) which should be replaced. However please let us know that the machine heats up correctly. Thank you so much in advance. We remain at your complete disposal and we look forward to receiving your kind feedback.’

I’m not convinced it’s a faulty LED, but have ordered a replacement anyway. I’ll update again when it arrives!

@DavecUK @Doram

New LED fitted, appears to have been that!

Thanks for the help & suggestions along the way.

Doram

Great to hear you managed to sort it! Where did you get the new LED?

Doram

Bella Barista. It’s advertised as a tank pilot light, but comes as the pair including the machine ready pilot LED.

The only problem is that the new water LED is much brighter than the old machine ready LED, so I think I’ll need to swap that over too 😆
