My delonghi perfecta plus esam5450 tells me to descale when the last descale was only 3 weeks ago. It is 18 months old and I usually only need to descale every few months. However, the last 3 times i have needed to descale every few weeks. Why? i have always looked after it and only ever use rain water. i would be grateful for your advice. Many thanks. marion

Hello, Here is a tip i wrote, see if this helps you.



Have you ever wondered, 'how do I descale my expresso machine?' First lets us understand what is exactly is scaling. The build up of minerals inside the hot parts of your coffee machine or espresso machine is commonly called lime scale. When lime scale builds up inside the Espresso machine, it slows down the water flow, reduces the boiler capacity and can prevent your coffee machine from working properly. To keep your Espresso machine operational at full order, it is important to descale it every three months. The time intervals between descaling depend upon many factors. Quality of your water and the amount of water running through the machine are the two main factors that decide the frequency at which you should descale your Espresso machine. The more you your machine, more often should you descale it. In some cities, in conjunction with a water filter you can use your coffee machine for a year or more without descaling at all. If you use less water by drinking espressos you'll need to descale less often than if you make cappuccinos.


Descaling products are widely available from stores that sell coffeemakers and espresso machines. Be sure that the product you buy to descale your Espresso machine is intended for this specific use only. Before you descale your Espresso machine, always unplug it and make sure that it is cold. Also, never immerse the appliance in water and nor should you use abrasive cleaning products or scouring materials on any part of your Expresso machine. In case your Espresso machine does not come with a instruction guide or booklet, then use a proper citric acid based descaling solution designed for espresso machines. This should be mixed and prepared as per the instructions on the bottle or packet. Once your Espresso machine has been descaled properly you would not be left wondering, 'how do I descale my expresso machine?', treat yourself to a great cup of coffee. Some popular models of Espresso machines are Krups EA8080 Espresseria Automatic, DeLonghi Magnifica EAM3200S, Krups Nespresso CitiZ & Milk XN 7106 Fire-engine red, DeLonghi Perfecta ESAM5400, DeLonghi PrimaDonna ESAM6600, DeLonghi Magnifica ESAM4200S, DeLonghi Perfecta ESAM5500 and Magimix Nespresso Citiz M190.

In order to keep your Tassimo machine operational at full order, it is important to descale it every three months. Descaling products are widely available from stores that sell coffeemakers and espresso machines. Be sure that the product you buy to descale your Tassimo machine is intended for this specific use only. Mix the descaling product directly in the water container, following the instructions provided on the descaling packaging. Then replace the water container on the machine. Place a large cup or mug on the cup stand, insert the cleaning disc, bar code down and close the brew mechanism. As soon as the AUTO light illuminates, press and release the start/stop button. This will fill the brew cycle with descaling solution. Empty the cup and let the machine stand for 15 minutes. Then open the brew mechanism and close it again, leaving the cleaning disc in place. Repeat this step two more times for maximum descaling effectiveness.

Discard the remaining descaling agent from the water container, rinse it well and refill with fresh, cold water. Clean the machine by flushing water through it in the same manner and emptying the cup as it fills. Make sure that all the descaling solution has been completely rinsed away, and then flush two full water containers through the machine before using it again. Remove the cleaning disc, rinse and refill the water container and your Tassimo machine is ready to use. Also, before you descale your Tassimo machine, always unplug it. Also, never immerse the appliance in water and nor should you use abrasive cleaning products or scouring materials on any part of your Tassimo machine. This method works for most espresso machines, including some of these popular models: the DeLonghi Magnifica EAM3200S, DeLonghi Magnifica ESAM4200S, DeLonghi Perfecta ESAM5400, Gaggia 74507BCN Classic, Krups EA8080 Espresseria Automatic, DeLonghi PrimaDonna ESAM6600, the BC0255 DeLonghi coffee machine and the Krups Nespresso CititZ XN 7006.

It sounds to me you have short in the keypad controller system, from your description this is a very dangerous fire hazard situation, and the microwave in my view should replaced.

You need to return it to Target after you get an authorisation number to quote from them.
Contact your supplier first.

It sounds like the high voltage section may be on whenever the door is closed, likely due to a shorted relay on the control board, or possibly a problem with the door switches and mounts.

You should be able to find help at the DeLonghi customer service site.

Make sure the turntable guide is lined up properly and there is no debris caught in it. Examine the turn table bushing the tray sits on and make sure it is not worn or broken. Make sure the turntable is sitting down in the groove correctly. Lastly it may be the drive motor itself is bad. This is the small motor that turns the carousel. This motor is very difficult to replace and unless you are qualified you should not attempt this repair and leave it to a professional. This motor will cost from $40 to $75 plus the cost of having it replaced. You may want to consider buying a new microwave if this unit is over 5 years old. You could end up spending more to repair this one than a new one costs. Of course you can use it without the carousel.

uplug the micro wave for the same amout of time the dector go off and see what happen if it goes off check the battery and replace them and do the same as above test to see if dector is not working properly

no solution sorry but we also have a Neff mw/combi oven which keeps blowing for no apparent reason, the Neff repair man has looked at it 4 times and practically replaced every component -power module, operating module,relay board, door switches but it`s just gone again! The model is a H5972N0GB/01 and it is approx 3 yrs old, no problem for the first 2 years .Time to write to Neff -is yours the same model?

Yes this is usually caused by the touch assy, but $278 !!!!! Thats kinda steep considering the panel assy is only around 30-60 bucks!!! It will need the touch assy and even possibly the control board, because sometimes the logic IC gets fried and causes "ghost issues" as well.
