Lay Z Spa pump Troubleshooting with error codes E01: Unplug the pump. With one hand hold the pump and with the other hit the pump three times strong enough. Coleman is a household name for its camping products, but the company also has a line of spas in its business model. Coleman spas offer green options for these luxury tubs, using technology that reduces energy use and insulation to maintain water warmth. The surface should be solid so it can bear the weight of a water-filled hot tub including 4-6 persons. Once you found the best location clean the area and spread the ground cloth of Coleman Inflatable hot tub. Take Coleman Lay Z Spa out from its package and spread it on the center of the ground cloth.

Unplug the spa pump, remove from the liner and drain 20% of the water from the spa. Refill this with fresh water. Start the Salt Chlorinator System.

E02 Code On Coleman Hot Tub

Coleman Spa E02

Hi,
I have a Lay-Z spa from 2012. It's the platinum/vegas version with the heater that can only heat or bubble, not both at the same time.
The pump worked for just over a year, only need occasional cleans, but it's now in a state where whilst the BUBBLES work fine, the pump itself won't pump around water to filter.
After power on, if the filter/heater setting is selected I get a few seconds of silence then beeps with E02 displayed
E02 seems to be a water flow issue.
I tried backflushing - in fact I can squirt water through either way around, and it comes out the other end just fine (in->out or out->in)
At no point is there ANY noise.
This suggests to me that the pump has failed/has bad connection
If it was the flow meter I suspect it would pump for a while then stop.
I've dismantled the unit but it's not clear what to check. The large 'pump' unit seems clear of debris -- but thinking about it now perhaps this is just the air blower
Where is the pump in this unit?
Any recomendations on getting a spare part?
I feel a little guilty posting about this cheap temporary unit here. One day I'll invest in a proper spa.... this one I acquired from someone who no longer wanted it!
many thanks
Nigel.
