DeLonghi BCO430 Troubleshooting
DeLonghi Espresso and Coffee Maker
The steam wand does not heat up after a few uses
The temperature of the steam wand stays cool after initiating the use of it
Preheat the Steam Wand
Turn on the steam wand and run a cycle through the espresso machine to allow for the steam wand to warm up.
Steam Wand May Be Blocked By Build-up
After each use ensure that the steam machine is thoroughly cleaned by using a warm towel to wipe the residue off of the steam wand.
Blocked coffee grinder when using expresso mode
The coffee grinder may have built up from previous uses causing a delay in espresso mode
Old Coffee Beans May Cause Build-up
Coffee beans from previous use that are not cleaned out thoroughly will cause the coffee grinder to be blocked. Take apart the parts of the coffee grinder and wash each one with soap and warm water.
Overfill Of Coffee Beans In Grinder
This device works best when there are less coffee beans in the grinder allowing for the beans to become more fine.
Milk frother does not function
The milk frother isn’t frothing the milk properly
Nozzles may be dirty
Check the nozzles of the frother to make sure that there isn’t any milk debris inside. Make sure that the machine is off and unplugged to clean the nozzle. Twist the nozzle to the right to remove the outer part of the nozzle. Next, pull the tip down until the piece comes off. Rinse thoroughly to remove all the debris inside, dry and twist them back in.
To keep the machine performing and heating up properly, you should always clean after using them to prevent excessive build-up.
Not using correct type of milk
When frothing your milk, make sure it is cold. De’Longhi recommends using semi-skimmed milk at refrigerator temperature for the best results.
Steam Notifier Light Will Not Turn On
Steam Light won’t turn on when you use the on/off button
The Light Bulb Inside Is Broken
If the lightbulb is broken, then it means you have to replace it.
Preventing leaks from the base of the water tank
Water Tank May Be Cracked
Over time of use, the water tank can eventually crack. When washing the tank, do not put it into the dishwasher, hot water can damage the plastic. Check regularly in the case of any damage.
Seals For The Tank Are Worn Out
A defective seal on the bottom of the tank can cause water to leak. To check if this is the problem, fill the tank with water and look for any leaking from below. If this is the cause, the seal will have to be removed and replaced.
Pump Hose Has Split Open
Hoses that pump the water go through high water pressures and eventually will burst over time or can be damaged by built-up limestone inside the outlet. It is recommended to regularly clean these hoses.
Espresso coffee dispensed cold
Coffee is not hot/warm when dispensed
Preheating was not done/completed
Assure the machine is on by pressing the ON/OFF button and check the power light. After the coffee drip light comes on, press the coffee drip button.
Scale in the water circuit
The mineral build-up in the coffee unit may disrupt preheating. To descale the unit, dilute the provided descaler solution in water. (If you do not have a descaler solution, use vinegar.) Remove the water filter before turning the machine on, then allow ¼ of the solution through the coffee dripper by pressing the coffee drip button. Leave the solution for at least 5 minutes before repeating this process 3 to 4 times. Rinse the tank and fill with clean water to remove the rest of the solution.
