Hi


Thanks for using FixYa. From what you have described the issue is with the water pump that has gone bad and should be replaced. As everything else is working fine so don’t think the issue is related to anything else, when the pump goes bad it should be replaced as it cannot be repaired. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

Is the thermostat pulling in the relay? There is a relay that should pull in with the thermostat. Either the transformer that goes to the thermostat could be bad and not pulling in the relay.

How do I clean / sanitize my sunbeam humidifier swm5250 with bleach?


I'm no expert, but a friend of mine loaned me her humidifier recently and she just put some bleach and water in the tank and cleaned the tank with that. It did leave a smell of bleach in the tank that could be smelled any time it ran, but after a few refillings, it went away, and I figure if it smells there must be a little left, which means it should clean the working parts fairly well too. (while you're running it the first few times) And the medicine tray in the SWM5250 is dishwasher safe, so I would just run that through the dishwasher, but bleach should be fine for that too.

Do not know how to work/maintain swamp cooler


Make sure you have water to the unit, the water pump is on and the fan is working. No water=no cooling.

XP 2070 Won't Stop Beeping


Okay, I had the same problem, started beeping and lights flashing one day, unplugged it and it was okay for a few days then this started happening more often until the machine just beeped and blinked all the time and would not make espresso. When I called Krups customer service I was told it sound like a circuit board problem and to send it in, yes its under warranty but I have to pay shipping both ways, so I decided to check it out myself. So here is the bottom line and what worked for me, I removed the espresso screen (above coffee grounds holder, 1 phillips screw) and ran 4 tank fulls of descaler thru the machine. the hard part was getting it to pump thru the machine. I found if I ran water thru the hot water/steam nozzle first I could get it to run 1 or 2 cycles, I also found that by removing the water tank and turning the system on for a few seconds and running pump dry (not recommended) I could get it to cycle without blinking for a few turns. Ran the 4 tanks of descaler thru, then ran 4-5 tanks of water thru into a bowl until it ran thru clean. The machine is 4 months old and I was shocked at the amount of crud that came out. It now runs fine and no more blinking, If indeed this is the fix for this you would think someone at Krups would have a clue, but I guess there a useless a the owners manual for the xp2070.
Thanks and I hope this helps.
John
