Flashing blue light under washing machine. If this is the case you may be facing a problem with the belt or idler pulley. Flashing or Blinking Display means the washer is in standby mode. Flashing blue indicates that the battery is not charging.
If the machine has no power and you have a blue light on the battery please check the Max button light and count the flashes for the following. The flashes may appear quickly - so it will be best to check twice. Not all the time just a sporadic burst ever few seconds.
Very slow pulsing light blue. What you can do instead is power cycle it. HELP PLEASE - Answered by a verified Appliance Technician.
We recomend a regular maintenance wash cycle. I noticed there were blue sparks coming from under the machine as it was spinning. A flashing red light indicates that there is a fault please call.
On the side of the Cleaner head locate the end cap. There should be a small padlock icon along with directional arrows to help you unlock the end cap. The blinking clean light indicates the control did not see a 2 degree or a 4 degree increase in water temperature during the first 8 minutes of the main wash.
