Coleman E05: thermometer connection
E05 means the pump's thermometer connection has issues. The table gives two reasons: the connectors do not work properly, or the thermometer is broken. This line is from Coleman owner's manual 90427E, document 303021298886, for pumps S100105 and S100205. The only printed solution is Bestway USA support.

When to call a technician
Call a technician now if
- The breaker or the RCD trips when the pump is plugged in.
- You smell burning, see melted plastic, or the water is too hot to touch.
- The code comes back after one reset.
Also call for these, from the manual
- Contact Bestway USA for E05. The manual does not give a home repair for the thermometer connection. Do not open the pump.
Questions
Does this manual say to unplug for five minutes?
No. Page 17 of manual 90427E only sends E05 to the Bestway USA support page. A five-minute restart is not printed on this code. Do not take that step from a different brand's manual.
