Jura S9 Loud 'pop' and then water from the bottom

Recently, over several weeks, the water flow from my Jura S9 has been poor. Very slow to dispense coffee and sometimes the stream even stops and restarts. Today, while dispensing, there was a loud pop, like a circuit breaker popped. I could hear sizzling after that. The machine kept going, but no more coffee came out. After that, I tried a rinse cycle. It ran, but the water came out from the bottom instead of the spout.
