Capresso coffee maker turns on but does not heat the water; cold water drips or nothing comes out.

Safety first: Unplug the coffee maker and allow it to cool. Heating components can retain heat.

Steps:

• Listen during brew attempt: Start a brew and listen for clicking relays or boiling sounds. Silence plus no heat suggests a heater circuit issue.
• Check for descaling need: Severe scale can reduce heating efficiency. Run a full descaling cycle per Capresso instructions. If there is still no heat, the issue is likely electrical.
• Inspect for burnt smell: A burnt odor from the base may indicate a failed heater or fuse.
• Internal checks (advanced): With the unit unplugged and bottom cover removed, inspect heater terminals and wiring for burns or disconnections. Do not bypass any thermal fuses.
• Component replacement: A failed thermoblock, boiler, or thermal fuse must be replaced with the correct Capresso part. This is typically an advanced repair.
