I have replaced the filter in out Smiths Medical Level 1 Convec. warmer and reset it. When plugged in, the "wrench" icon is blinking and the "occlusion" light is solid. I have checked and there is no occlusion and the cord is connected correctly on both ends, inside the hose. What do I do now?

If the "wrench" icon is blinking and the "occlusion" light is solid on a Smiths Medical Level 1 Convective Warmer after replacing the filter, remove the power plug from the mains, check the hose and thermistor cable connections, restart the unit, select a temperature, and determine if the problem persists before placing the unit back in service.
