When this happens, some models may display a heater error on the control panel as flashing LEDs for Heavy and Delicate or Heavy and Quick.\u00a0<\/span>\r\n\r\n<b>Read more: <\/b><a href=\"https:\/\/www.appliancepartspros.com\/b\/dishwasher-insulation-and-why-is-it-important\/\"><b>What is Dishwasher Insulation and Why is it Important?<\/b><\/a>\r\n<h2><strong>Safety precautions<\/strong><\/h2>\r\n<span style=\"font-weight: 400;\">When working on any appliance, remember to keep safety first. Here are some tips to keep in mind:\u00a0<\/span>\r\n<ul>\r\n \t<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.<\/span><\/li>\r\n \t<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Turn off the water supply at the outlet before beginning repairs to any appliance parts that hold water.
